QJEEM25Chdb8a: JEE Main 2025 Chemistry - Class 11 JEEM25Chdb8a Solution: Standard entropies of and are 70, 50 and respectively. The…

Standard entropies of $\mathrm{X}_2, \mathrm{Y}_2$ and $\mathrm{XY}_5$ are 70, 50 and $110 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}$ respectively. The temperature in Kelvin at which the reaction

$$\frac{1}{2}{\mathrm{X}}_2+\frac{5}{2}{\mathrm{Y}}_2\rightleftharpoons {\mathrm{XY}}_5\mathrm{\Delta }{\mathrm{H}}^{\ominus }=-35\mathrm{kJ}{\mathrm{mol}}^{-1}$$

will be at equilibrium is __________ (Nearest integer)
