Question

what is the activation energy, $e_a$, for this reaction? 90 j 50 j 80 j 30 j

Explanation:

Step1: Identify activation energy on graph

Activation energy is the energy difference between reactants and transition - state.

Step2: Read values from graph

Assume reactant energy is 30 J and transition - state energy is 80 J.
$E_a=80 - 30$

Answer:

50 J
