Which of the following is not true when comparing an uncatalyzed reaction to the same reaction with a catalyst?
A)The catalyzed reaction will be faster.
B)The catalyzed reaction will have a different ∆G.
C)The catalyzed reaction will have lower activation energy.
D)The catalyzed reaction will not consume any of the catalyst.

Question

Quizplus · Accepted Answer

The presence of a catalyst does not affect the thermodynamics of a reaction, so the ∆G of the catalyzed reaction will be the same as the uncatalyzed reaction. However, a catalyst can lower the activation energy required for the reaction, making it faster, and will not be consumed in the reaction, so options A, C, and D are true.
