Question

23 refer to the graph below. which statement below best explains reaction 3. (2pts) a reaction 3 is the same as reaction 1, but faster. b reaction 3 requires a greater activation energy than reaction 2. c reaction 3 most likely occurred in the presence of an enzyme. d reaction 3 takes longer to occur than reaction 2.

Explanation:

Enzymes lower the activation - energy of a reaction. Reaction 3 has a lower activation energy compared to Reaction 1 and 2. This is characteristic of a reaction with an enzyme present.

Answer:

C. Reaction 3 most likely occurred in the presence of an enzyme.
