Which statement best describes the diagram? the catalyzed reaction passes through c. the energy of the catalyst is shown by a. the reaction pathway through b is faster. the energy of the reactants with catalyst is at d.

Answer is: The catalyzed reaction passes through C.

A is energy of reactants.

D is energy of product of reaction.

C is activation energy with catalyst, it is lower than B and reaction with the catalyst is faster.

B is activation energy without catalyst.

Chemical reactions require heat or an input of energy to occur, this is activation energy.

By lowering activation energy, reaction need less heat. Reactions occur faster  with a catalyst because they require less activation energy.

Because activation energy of the process becomes less, that means that catalyst is used.

The catalyzed reaction passes through C.
