How is the presence of a catalyst represented in an energy level diagram?

A) By the letter "C" at the transition state site
B) By a lowered energy of activation
C) By a heightened reactant initial energy
D) By a lowered product final energy

Energy Level Diagram

A visual representation of the energy states of electrons in an atom or molecule and the transitions between these states.

Catalyst

A substance that increases the rate of a chemical reaction without being consumed in the reaction, often used in industrial processes to enhance efficiency and specificity.

Activation

The process of making something active or operative, often referring to the initiation of a chemical reaction or the stimulation of a biological process.
