Ozone (O₃) in the atmosphere can react with nitric oxide (NO): O₃(g) + NO(g) $\rarr$NO₂(g) + O₂(g).Calculate the $\Delta$G^$\circ$ for this reaction at 25^$\circ$C. ($\Delta$H^$\circ$ = -199 kJ/mol, $\Delta$S^$\circ$ = -4.1 J/K·mol) A) 1020 kJ/mol B) -1.22 * 10³ kJ/mol C) 2.00 * 10³ kJ/mol D) -1.42 * 10³ kJ/mol E) -198 kJ/mol

Question

Quizplus · Accepted Answer

The Gibbs free energy change ($\Delta G^\circ$) is calculated using the formula: $\Delta G^\circ = \Delta H^\circ - T\Delta S^\circ$. Convert $\Delta S^\circ$ to kJ by dividing by 1000: $-4.1 \, \text{J/K·mol} = -0.0041 \, \text{kJ/K·mol}$. At 25°C (298 K), $\Delta G^\circ = -199 \, \text{kJ/mol} - (298 \, \text{K} \times -0.0041 \, \text{kJ/K·mol}) = -198 \, \text{kJ/mol}$.
