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$

$p$-Amino- $N, N$-dimethylaniline is added to a strongly acidic solution of ${X}$. The resulting solution is treated with a few drops of aqueous solution of ${Y}$ to yield blue coloration due to the formation of methylene blue. Treatment of the aqueous solution of ${Y}$ with the reagent potassium hexacyanoferrate$(II)$ leads to the formation of an intense blue precipitate. The precipitate dissolves on excess addition of the reagent. Similarly, treatment of the solution of ${Y}$ with the solution of potassium hexacyanoferrate$(III)$ leads to a brown coloration due to the formation of ${Z}$.

$1.$ The compound ${X}$ is

$(A)$ $\mathrm{NaNO}_3$ $(B)$ $\mathrm{NaCl}$ $(C)$ $\mathrm{Na}_2 \mathrm{SO}_4$ $(D)$ $\mathrm{Na}_2 \mathrm{~S}$

$2.$ The compound ${Y}$ is

$(A)$ $\mathrm{MgCl}_2$ $(B)$ $\mathrm{FeCl}_2$ $(C)$ $\mathrm{FeCl}_3$ $(D)$ $\mathrm{ZnCl}_2$

$3.$ The compound ${Z}$ is
