In this reaction $SbF_5$ acts as
| 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$

$(II)$ $A$ to $B$ precentage of $p-$character in $P-Cl$ bond increases
$(III) $ Number of covalent bond in $A$ and $B$ are same
$(IV)$ $B$ is product of Lewis acid-base interaction which is associated with super octet molecule only
