The values of pressure equilibrium constant recorded at different temperatures for the following equilibrium reaction have been given below $$\mathrm{A}(\mathrm{~g}) \rightleftharpoons \mathrm{B}(\mathrm{~g})+\mathrm{C}(\mathrm{~g}) $$

$\displaystyle \frac{1}{\mathrm{~T}}\left(\mathrm{~K}^{-1}\right)$	$\displaystyle \log _{10} \mathrm{~K}_{\mathrm{p}}$
$\displaystyle 0.05$	$\displaystyle 3.5$
$\displaystyle 0.06$	$\displaystyle 2.5$
$\displaystyle 0.07$	$\displaystyle 1.5$

The magnitude of $\displaystyle \frac{\Delta \mathrm{H}^{\circ}}{\mathrm{R}}$ calculated from the above data is $\displaystyle \_\_\_\_$. (Nearest integer)
