Question

In the graph above, the activation energy of the catalyzed reaction is

Options

A) 100KJ

B) 300KJ

C) 250KJ

D) 200KJ


The correct answer is A.

Explanation:

Activation energy of catalysed reaction is the small curve inside while the activation energy of the uncatalysed is the big curve outside.
Therefore activation energy of the catalysed reaction = Activation complex of the catalysed reaction - reactant = 200 - 100 = 100KJ.

  • I think the correct answer is D. If not please share more light thanks

  • Activation energy of catalysed reaction is the small curve inside while the activation energy of the uncatalysed is the big curve outside.
    Therefore activation energy of the catalysed reaction = Activation complex of the catalysed reaction - reactant = 200 - 100 = 100KJ.
