Question
By using Le Chatelier’s principle, explain the effect of addition of a catalyst on the composition of equilibrium mixture.
✓
Answer
- When a catalyst is added to the equilibrium mixture, the rates of forward and reverse reactions increases to the same extent. Hence, the position of equilibrium remains unaffected.
- A catalyst does not change the composition of equilibrium mixture. The equilibrium concentrations of reactants and products remain same and catalyst does not shift the equilibrium in favour of either reactants or products.
- The value of equilibrium constant is also not affected by the presence of a catalyst.
