question 49

Multiple Choice

For the reaction 2NO(g) + O₂(g) $\rarr$ 2NO₂(g) if initially P(NO) = 1.5 atm, P(O₂) = 1.4 atm, and P(NO₂) = 2.0 atm, calculate $\Delta$ G for this reaction at 25 ^$\circ$ C. The following data is valid at 25 ^$\circ$ C: $\begin{array}{|c|c|}\hline & \Delta \mathrm{G}_{\mathrm{f}}{ }^{\circ}(\mathrm{kJ} / \mathrm{mol}) \\\hline \mathrm{NO} & 86.7 \\\hline \mathrm{NO}_{2} & 51.8 \\\hline\end{array}$

• A) -69.9 kJ/mol
• B) -69.2 kJ/mol
• C) 522.1 kJ/mol
• D) -79.9 kJ/mol
• E) -35.0 kJ/mol
