Temperature $\quad$ Equilibrium constant
$\begin{array}{ll} T _{1}=25^{\circ} C & K _{1}=100 \\ T _{2}=100^{\circ} C & K _{2}=100\end{array}$
The values of $\Delta H ^{\circ}, \Delta G ^{\circ}$ at $T _{1}$ and $\Delta G ^{\circ}$ at $T _{2}$ (in $kJ\, mol ^{-1}$ ) respectively, are close to $\left[\right.$ Use $\left. R =8.314\, JK ^{-1} mol ^{-1}\right]$

The decreasing order of the rate of the above reaction with nucleophiles $(Nu^-)$ $A$ to $D$ is
$[Nu^-=(A) \,PhO^-, (B)\,AcO^-, (C)\, HO^-, (D)\, CH_3O^-]$
