Chemistry - Thermodynamics - II Question with Solution | TestHub

$\begin{array}{rl}& {\mathrm{N}}_2(\mathrm{g})+3{\mathrm{H}}_2(\mathrm{g})\to 2{\mathrm{NH}}_3\\ & \Delta {\mathrm{H}}^{\circ }=-\mathrm{ve}\\ & \Delta {\mathrm{S}}^{\circ }=-\mathrm{ve}\end{array}$
(As gaseous moles decreases).
(1) As temperature increases $\frac{-\Delta {\mathrm{H}}_R^0}{T}$, decreases
(2) $\Delta {\mathrm{G}}^{\circ }=-\mathrm{RT}\ln {\mathrm{K}}_{\mathrm{eq}}$
$\mathrm{R}\ln {\mathrm{K}}_{\mathrm{eq}}=-\frac{\Delta {\mathrm{G}}^0}{\mathrm{T}}$
(on increasing temperature in exothermic reaction ${\mathrm{K}}_{\text{eq }}$ decreases)
$\Delta {\mathrm{H}}^{\circ }$ and $\Delta {\mathrm{S}}^{\circ }$ are almost constant with temperature.
