Consider the following transformation involving first order elementary reaction in each step at constant temperature as shown below.

$\mathrm{A}+\mathrm{B} \underset{\text { Step } 3}{\text { Step } 1} \mathrm{C} \xrightarrow{\text { Step } 2} \mathrm{P}$

Some details of the above reaction are listed below.

Step

Rate constant $\left(\sec ^{-1}\right)$

Activation energy 

$\left(\mathrm{kJ} \mathrm{mol}^{-1}\right)$

$1$ ${k}_1$ $300$
$2$ ${k}_2$ $200$
$3$ ${k}_3$ $\mathrm{Ea}_3$

If the overall rate constant of the above transformation (k) is given as $\mathrm{k}=\frac{\mathrm{k}_1 \mathrm{k}_2}{\mathrm{k}_3}$ and the overall activation energy $\left(E_2\right)$ is $400 \mathrm{~kJ} \mathrm{~mol}^{-1}$, then the value of $\mathrm{Ea}_3$ is $\qquad$ $\mathrm{kJ} \mathrm{mol}^{-1}$ (nearest integer)
