Chapter 18, Problem 30QP

From the values of $\Delta H\text{ and }\Delta S$, predict which of the following reactions would be spontaneous at $\text{25°C}$: reaction $\text{A: }\Delta H\text{ = 10}\text{.5 kJ/mol, }\Delta S\text{ = 30 J/K mol; reaction B: }\Delta H\text{ = 1}\text{.8 kJ/mol, }\Delta S\text{ = -113 J/K }\cdot \text{ mol}$. If either of the reactions is nonspontaneous at $\text{25°C}$, at what temperature might it become spontaneous?
