Question

For a chemical reaction, the activation energy for the forward reaction is +181 kJ and the activation energy for the backward reaction is +62 kJ. What is the overall energy change for the forward reaction?

Answer 1

Given :

For a chemical reaction, the activation energy for the forward reaction is +181 kJ and the activation energy for the backward reaction is +62 kJ.

To Find :

The overall energy change for the forward reaction.

Solution :

The overall energy change for the forward reaction is :

`\Delta E_f = E_f - E_b\\\\\Delta E_f = 181 - 62 \ Kj\\\\\Delta E_f = 119 \ Kj`

Therefore, the overall energy change for the forward reaction is 119 Kj.
