Calculate the boiling point of a substance $\mathrm{A}$ (liquid) $(?\mathrm{H}=62.3\mathrm{kJ};?\mathrm{S}=144.5$ $\mathrm{J}/\mathrm{K})$. Report your answer in ${}^{?}\mathrm{C}$. You answer: $\times {}^{?}\mathrm{C}$ Question 3 Under what temperature conditions would the following reaction occur spontaneously? $2\mathrm{NO}\text{ (gas) }+{\mathrm{O}}_2\text{ (gas) }?2{\mathrm{NO}}_2\text{ (gas) }?{\mathrm{H}}^0=?114.1\mathrm{kJ}/\mathrm{mol}$ Select one: a. nonspontaneous at all temperatures. b. spontaneous at all temperatures. c. spontaneous at low temperatures. d. spontaneous at high temperatures.
