Calculate H^0 for a reaction if S^0 = 120 JK^ -1 and G^0 = 28000 J

MHT CET 2025 Chemistry question

Calculate for a reaction if = 120 and = 28000 J

(A)15.94 kJ
(B)31.83 kJ
(C)94.12 kJ
(D)63.76 kJCorrect

Answer: (D)

Solution

Use the Gibbs equation at the standard temperature T = 298 K (not stated in the question, but standard values refer to 298 K): , so H^0G^0S^0$ = 28000 +
