Standard entropies of $\displaystyle \mathrm{X}_2, \mathrm{Y}_2$ and $\displaystyle \mathrm{XY}_5$ are $\displaystyle 70,50$ and $\displaystyle 110 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ respectively. The temperature in Kelvin at which the reaction $$\frac{1}{2} \mathrm{X}_2+\frac{5}{2} \mathrm{Y}_2 \rightleftharpoons \mathrm{XY}_5 \Delta \mathrm{H}^{\Theta}=-35 \mathrm{~kJ} \mathrm{~mol}^{-1} $$ will be at equilibrium is $\displaystyle \_\_\_\_$ (Nearest integer)
