Quizplus · Accepted Answer

The Gibbs free energy change ($\Delta$G°) can be calculated using the formula: $\Delta$G° = $\Delta$H° - T$\Delta$S°. Convert $\Delta$S° to kJ by dividing by 1000: $\Delta$S° = -0.0041 kJ/K·mol. At 25°C (298 K), $\Delta$G° = -199 kJ/mol - (298 K)(-0.0041 kJ/K·mol) = -198 kJ/mol.
