Chemical Kinetics Ques 58
58. For an exothermic reaction, the energy of activation of the reactants is
[1994]
(a) equal to the energy of activation of products
(b) less than the energy of activation of products
(c) greater than the energy of activation of products
(d) Sometimes greater and sometimes less than that of the products

Answer:
Correct Answer: 58.(b)
Solution:
(b) $E _{a \text{ (Forward) }}+\Delta H=E _{a \text{ (backword) }}$
For Exothermic reaction, $\Delta H=-ve$ and
$\therefore$ activation energy of reactant is less than the energy of activation of products.
