Questions: Consider the reaction profile shown below. Identify the intermediate(s). A 1 B 2 C 3 D 4 E 5

Solution Steps

The reaction profile shows the change in enthalpy (H) as the reaction progresses along the reaction coordinate. Peaks represent transition states, and valleys represent intermediates.

Transition states are the highest points on the reaction profile. In this diagram, points 2 and 4 are the transition states.

Intermediates are the species that exist at the local minima between transition states. In this diagram, point 3 is the intermediate.
