Chapter 10, Problem 10.50PAE

For the reaction $\text{NO}\left(\text{g}\right)+{\text{NO}}_{\text{2}}\left(\text{g}\right)\to {\text{N}}_{\text{2}}{\text{O}}_{\text{3}}\left(\text{g}\right)$ , use tabulated thermodynamic data to calculate $\Delta \text{H}°$ and $\Delta \text{S}°$. Then use those values to answer the following questions.

(a) Is this reaction spontaneous at 25°C? Explain your answer.

(b) If the reaction is not spontaneous at 25°C, will it become spontaneous at higher temperatures or lower temperatures?

(c) To show that your prediction is accurate, choose a temperature that corresponds to your prediction in part (b) and calculate $\Delta \text{G}$ . (Assume that both enthalpy and entropy are independent of temperature.)
