Chemical Kinetics Question 347

Question: For the exothermic reaction $ A+B\to C+D,\Delta H $ is the heat of reaction and $ E_{a} $ is the energy of activation. The energy of activation for the formation of A + B will be

Options:

A) $ E_{a} $

B) $ \Delta H $

C) $ E_{a}+\Delta H $

D) $ \Delta H-E_{a} $

Show Answer

Answer:

Correct Answer: C

Solution:

[c] For the exothermic reaction the energy of products is always less than the reactants. If $ {E_{a}} $ is the energy of activation for the forward reaction, the energy of activation for backward reaction is $ E_{a}+\Delta H $
