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 $
