Solution: The energy profile of a reaction, showing transition states and an intermediate.For this profile, is it easier for a molecule of the intermediate to convert to reactants or products?

Problem

A graph has reaction progress on the x-axis and potential energy on the y-axis. Both axes are unscaled.  Potential energy increases from the reactants to two peaks that are each a transition state with a trough between them that is the intermediates. The first peak is higher than the second. After the second transition state, potential energy declines to the products, which have higher potential energy than the reactants.


The energy profile of a reaction, showing transition states and an intermediate.

For this profile, is it easier for a molecule of the intermediate to convert to reactants or products?
