Quizplus · Accepted Answer

Catalyst I has a lower activation energy compared to catalyst II, which means it will require less energy to initiate the reaction. This will result in a higher rate of the reaction, making catalyst I more efficient. The choice cannot be D as activation energy is sufficient to determine the relative efficiency of two catalysts.
