For a reaction ${\mathrm{C}}_{\text{(graphite) }}+2{\mathrm{H}}_{2(\mathrm{g})}\to {\mathrm{CH}}_{4(\mathrm{g})},\Delta {\mathrm{H}}^{\circ }=-75\mathrm{KJ}$ at 300 K and 1 atm . The standard entropies of ${\mathrm{C}}_{(\text{graphite })},{\mathrm{H}}_{2(\mathrm{g})}$ and ${\mathrm{CH}}_{4(\mathrm{g})}$ are $6,130.6$ and $186.2\frac{\mathrm{J}}{\mathrm{Kmol}}$ respectively. $\Delta {\mathrm{S}}_{\text{univ }}($ in $\frac{\mathrm{J}}{\mathrm{K}})$ for the reaction will be :-
