[Olympiad] For the reaction A(g) + B(g) ⇌ C(g), the equilibrium constant Kp is 2.0 × 10³ at 298 K. Calculate ΔG° for the reaction.
-
-9.5 kJ/mol
-
-18.8 kJ/mol
-
+18.8 kJ/mol
-
-25.6 kJ/mol
📝 Detailed explanation
ΔG° = -RT ln(K).
ΔG° = -(8.314)(298) ln(2000) = -(2477.57)(7.60) = -18831 J/mol ≈ -18.8 kJ/mol.
