If $O _{2}$ gas is bubbled through water at $303 \;K$, the number of millimoles of $O _{2}$ gas that dissolve in 1 litre of water is (Nearest Integer) (Given : Henry's Law constant for $O _{2}$ at $303 \;K$ is $46.82 \;k$ bar and partial pressure of $O _{2}=0.920 \;bar$ ) (Assume solubility of $O _{2}$ in water is too small, nearly negligible)

A reaction takes place in three steps with individual rate constant and activation energy as follows

	Rate constant	Activation energy
Step $1$	$k_1$	$E_{a1} = 180\ kJ/mol$
Step $2$	$k_2$	$E_{a2} = 80\ kJ/mol$
Step $3$	$k_3$	$E_{a3} = 50\ kJ/mol$

If overall rate constant, $k = {\left( {\frac{{{k_1}{k_2}}}{{{k_3}}}} \right)^{2/3}}$ ,then overall activation energy of the reaction will be .......... $ kJ/mol$
