Exemplar Problems

Problem 4 : Consider a reversible reaction that reaches equilibrium. If the concentration of reactants is increased while keeping the temperature constant, explain the effect on the Gibbs free energy change (∆G) of the reaction.

Solution :

If the concentration of reactants is increased while keeping the temperature constant, the reaction will shift towards the products to reach a new equilibrium. This means that the Gibbs free energy change (∆G) of the reaction becomes more negative, indicating that the reaction becomes more spontaneous.
