For a reversible chemical reaction where the forward process is exothe...
Explanation:
In a reversible chemical reaction, the reaction can occur in both the forward and backward directions. The forward process is exothermic, which means it releases energy in the form of heat.
Activation Energy:
Activation energy is the minimum amount of energy required for a reaction to occur. It is the energy barrier that must be overcome for the reactants to transform into products.
Comparison of Activation Energies:
a) The backward reaction has higher activation energy than the forward reaction: This means that more energy is required for the backward reaction to occur compared to the forward reaction.
b) The backward and the forward processes have the same activation energy: This means that the energy barrier for both the forward and backward reactions is the same.
c) The backward reaction has lower activation energy: This means that less energy is required for the backward reaction to occur compared to the forward reaction.
d) No activation energy is required at all since energy is liberated in the process: This statement is incorrect. Activation energy is always required for a reaction to occur, regardless of whether it is exothermic or endothermic.
Explanation of the Correct Answer:
The correct answer is option 'A' - The backward reaction has higher activation energy than the forward reaction. This means that more energy is required for the backward reaction to occur compared to the forward reaction.
In an exothermic reaction, the forward process releases energy as heat. This energy is used to overcome the activation energy barrier for the forward reaction. Since the forward reaction is exothermic, the energy released is greater than the activation energy required, making the forward reaction favorable.
On the other hand, the backward reaction is endothermic because it is the reverse of the exothermic forward reaction. In order for the backward reaction to occur, the energy barrier or activation energy must be overcome. Since the backward reaction is endothermic, it requires more energy to overcome the activation energy barrier compared to the forward reaction. Therefore, the backward reaction has a higher activation energy than the forward reaction in a reversible exothermic reaction.
