1.	Standard molar entropies of Mg_((s)) , C_((s)), MgO_((s)) & CO_((g)) respectively are S_1,S_2,S_3, & S_4 J//K//mol. Then DeltaS_("sys") for MgO_((s)) + C_((s)) rarr Mg_((s)) + CO_((g))
Answer» `S_1 + S_2 + S_3 + S_4` `(S_1 + S_4) - (S_2 + S_3)` `(S_2 + S_3) - (S_1 + S_4)` `(S_4 - S_3)` ANSWER :B
