Chemical Kinetics Question 347

Question: For the exothermic reaction A+BC+D,ΔH is the heat of reaction and Ea is the energy of activation. The energy of activation for the formation of A + B will be

Options:

A) Ea

B) ΔH

C) Ea+ΔH

D) ΔHEa

Show Answer

Answer:

Correct Answer: C

Solution:

[c] For the exothermic reaction the energy of products is always less than the reactants. If Ea is the energy of activation for the forward reaction, the energy of activation for backward reaction is Ea+ΔH
