Question

The value of activation energy for backward reaction in any reversible reaction is :-
​

Answer 1

Answer:

is the sum of the enthalpy (delta H) and the activation energy (Eact) for the forward reaction.

Explanation:

The energy diagram would look something like this. So the activation energy for the reverse reaction is the sum of the enthalpy (delta H) and the activation energy (Eact) for the forward reaction. Note that the enthalphy change is negative for the forward reaction. It means that energy is released from the reaction
