| Rate constant | Activation energy | |
| Step $1$ | $k_1$ | $E_{a_1} = 180\,kJ /mol$ |
| Step $2$ | $k_2$ | $E_{a_2} = 80\,kJ /mol$ |
| Step $3$ | $k_3$ | $E_{a_3} = 50\,kJ /mol$ |
overall rate constant, $k = {\left( {\frac{{{k_1}{k_2}}}{{{k_3}}}} \right)^{2/3}}$ overall activation energy of the reaction will be ........ $kJ\,mol$
