Question

In a reversible reaction, the energy of activation of the forward reaction is 50 kcal. The energy of activation for the reverse reaction will be

• A. < 50 kcal
• B. 50 kcal
• C. either greater than or less than 50 kcal
• D.

  50 kcal

Answer 1

Answer: (C)

either greater than or less than 50 kcal

Answer 2

The activation energy of a reverse reaction decide whether the given reaction is exothermic or endothermic, so, the energy of activation of reverse
reaction is either greater or less than 50 kcal. In case of exothermic reaction, the activation energy for reverse reaction is more than activation energy of
the forward reaction and in case of endothermic reaction, the activation energy for reverse reaction is less than activation energy of the forward
reaction.
