Consider a reaction that occurs by the following one-step mechanism:
A 2 + B 2 → 2 AB
The potential energy profile for this reaction is shown below.
-The activation energy for the forward reaction is given by the difference in energy between which two reaction stages?

Question

Consider a reaction that occurs by the following one-step mechanism:

The potential energy profile for this reaction is shown below. 
-The activation energy for the forward reaction is given by the difference in energy between which two reaction stages?

Quizplus · Accepted Answer

The activation energy for the forward reaction is the energy difference between the reactants (stage 1) and the transition state/activated complex (stage 2), which is the highest energy point along the reaction path before forming the products.
