7 Important Chemical Equilibrium Examples You Should Know


In the present article, we intend to discuss about the important chemical equilibrium examples you should know. We can always witness a state corresponding to a system in which it is found that the reactant concentration and the product concentration both evidently remain unchanged and also further more changes across properties cannot be seen to occur in correspondence to the system.

  • Ionization of acids and bases
  • Buffer solution
  • Methanol production
  • Ethanol production
  • Ammonia production
  • Solubility equilibria
  • Equilibrium in chemical processes

Ionization of acids and bases

Here, we can say that there is a splitting up of molecules that are generally neutral giving rise to the charged ions when they come in contact with the solution is itself the ionization. In this case, there occurs a point at which we can see a rate of both forward as well as backward reactions to be same.

Thus, is nothing but the chemical equilibrium. i.e., the expenditure of reactants in the reaction is compromised by the reverse reaction producing the same without any loss. It is one of the chemical equilibrium examples.

At such equilibrium point, there will be no variation in the concentration of the reactants as well as the products in accordance with time. In the aqueous medium there will be a production of hydrogen ions when dissociation of the acids takes place in that medium.

Buffer solution

For the functioning of cells to be normal we need to maintain the pH of the respective substance. For this purpose, we require a solution generally referred as a buffer. Even in several chemical as well as biochemical processes also we may find a prime utility of the buffer solution. This is because of the mandatory need to control the pH. 

The ideal pH of blood so that there is a normal functioning in the human body is found to be 7.35. By the use of buffer solution, the reactant concentration and the product concentration both evidently remain unchanged and also further more changes across properties cannot be seen to occur in correspondence to the system. It is one of the chemical equilibrium examples.

Methanol production

The conditions that are experimentally found to be favourable for the production are referred as the compromise conditions. The forward reaction in turn the production of methanol is usually favoured by a temperature that is comparatively lower which is around 500K as the forward reaction that is responsible for generating a lesser moles of gas  is recognized to be an exothermic reaction.

Along with lower temperature, a higher pressure is also found to be in favour of the forward reaction. A copper catalyst may be of great use in order to increase the rection rate. It is one of the chemical equilibrium examples.

Ethanol production

The conditions that are experimentally found to be favourable for the production are referred as the compromise conditions. The forward reaction in turn the production of ethanol is usually favoured by a temperature that is comparatively lower approximately 570K as the forward reaction that is responsible for generating a lesser moles of gas is recognized to be an exothermic reaction.

Along with lower temperature, a higher pressure is also found to be in favour of the forward reaction. A phosphoric acid catalyst may be of great use in order to increase the rection rate. It is one of the examples of chemical equilibrium examples.

Ammonia production

The conditions that are experimentally found to be favourable for the production are referred as the compromise conditions. The forward reaction in turn the production of ammonia is usually favoured by a temperature that is comparatively lower i.e., around 670K as the forward reaction that is responsible for generating a lesser moles of gas is recognized to be an exothermic reaction.

Along with lower temperature, a higher pressure is also found to be in favour of the forward reaction. A iron catalyst may be of great use in order to increase the rection rate. It is one of the chemical equilibrium examples.

Solubility equilibria

In this case, the considered solid molecules intend to produce individual molecules that are found to be aqueous by undergoing the process of dissolving. Below given reaction is an example for the same,

H2O
C12H22O11(S) —————> C12H22O11 (aq)

Whereas, there is a production of positive as well as the negative ions separately by the occurrence of dissociation of ionic solids. i.e.,

 NaCl (s) ————————-> Na + (aq) + Cl  (aq )

The salt solutions are experimentally recognized to be a good conductors corresponding to the electricity as thus formed ions are responsible for carrying the electric current. It is one of the examples of chemical equilibrium examples.

Equilibrium in chemical processes

We can always witness a state corresponding to a chemical reaction in which it is found that the reactant concentration and the product concentration both evidently remain unchanged and also further more changes across properties cannot be seen to occur in correspondence to the system.

As we all know, in chemical reactions we find the interconversion of products and reactants through forward and backward reactions respectively.

There occurs a point at which we can see a same rate of both forward and backward reactions. Thus, is nothing but the chemical equilibrium. i.e., the expenditure of amount of reactants in the reaction is compromised by the reverse reaction producing the same without any loss. It is one of the chemical equilibrium examples.

What are the different types that are associated with the chemical equilibrium?

In general, we can witness two types of chemical equilibrium. i.e.,

  • Homogeneous equilibrium
  • Heterogeneous equilibrium

Homogeneous equilibrium

In this type of chemical equilibrium, we may observe that the products of the reaction happen to be in the same phase as that of the reactants.

 Heterogeneous equilibrium

In this type of chemical equilibrium, we may observe that the products of the reaction happen to be in a different phase when compared to that of the reactants.

Why chemical equilibrium is dynamic?

The chemical equilibrium can also be called as the dynamic equilibrium as, As we all know, in chemical reactions we find the interconversion of products and reactants through forward and backward reactions respectively.

There occurs a point at which we can see a same rate of both forward and backward reactions. Thus, is nothing but the chemical equilibrium. i.e., the expenditure of amount of reactants in the reaction is compromised by the reverse reaction producing the same without any loss.

Name the factors that influence the chemical equilibrium.

The factors that are proved to be influencing the chemical equilibrium are,

  • Change in concentration
  • Pressure change
  • Temperature change
  • Effect of catalyst
  • Addition of acids and bases

What do you mean by chemical equilibrium?

We can always witness a state corresponding to a system in which it is found that the reactant concentration and the product concentration both evidently remain unchanged and also further more changes across properties cannot be seen to occur in correspondence to the system.

As we all know, in chemical reactions we find the interconversion of products and reactants through forward and backward reactions respectively.

There occurs a point at which we can see the same rate of both forward and backward reactions. Thus, it is nothing but the chemical equilibrium. i.e., the expenditure of the number of reactants in the reaction is compromised by the reverse reaction producing the same without any loss.

Conclusion

As we all know, in chemical reactions we find the interconversion of products and reactants through forward and backward reactions respectively. There occurs a point at which we can see a same rate of both forward and backward reactions. Thus, is nothing but the chemical equilibrium.
