Question 1

A reaction has ΔH° = -60.9 kJ/mol and ΔS° = 266.6 J/K. Is this reaction spontaneous or nonspontaneous? At what temperature (if any) can the spontaneity be reversed?
◦ spontaneous, cannot be made nonspontaneous at any temperature
◦ nonspontaneous, can be made spontaneous at 228 K
◦ nonspontaneous, cannot be made spontaneous at any temperature
◦ spontaneous, can be made nonspontaneous at 228 K

Question 2

Calculate the standard free energy change at 25°C for the reaction

2 NO(g) + O2(g) → 2 NO2(g).



◦ -72.6 kJ
◦ -157.8 kJ
◦ -532.6 kJ
◦ -4.7 kJ
