Reason : It is the mechanism and not the balanced chemical equation for the overall change that governs the reaction rate.
$\mathrm{Eu}^{3+}, \mathrm{Lu}^{3+}, \mathrm{Nd}^{3+}, \mathrm{La}^{3+}, \mathrm{Sm}^{3+}$
Where $A$ is $PCl^+_4$ while $B$ is $PCl^-_ 6$
Which of the following statement is INCORRECT :
$(I)$ $B$ to $A$ involvement of number of $d-$orbital in hybridization increases
$(II)$ $A$ 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

$\begin{array}{|l|l|l|} \hline P_0\,\,(mmHg) & 250 & 300 \\ \hline t_{1/2}\,\,(minutes) & 135 & 112.5 \\ \hline \end{array}$
The order of reaction is -
