Total: 44

Solution:

Concept:

Activation energy is the energy difference between the reactants and the activated complex for the catalyzed reaction path.

Explanation:

From the graph, the reactants are at

100\,\text{kJ}

and the catalyzed activated complex is at

300\,\text{kJ}

E_a = 300 - 100 = 200\,\text{kJ}

Answer:

200\,\text{kJ}
