|
True
|
|
|
False
|
|
|
Either A or B
|
|
|
None of the above
|
Explanation:
Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-2: -The correct answer is option ‘a’ catalysts increase the rate of the reaction by reducing the free energy of the transition state, which lowers the activation energy.
Detailed explanation-3: -A catalyst is a substance that increases the rate of a chemical reaction by lowering the activation energy without itself being consumed by the reaction.
