Question 1

For the reaction N2(g) + 2 O2(g) → 2 NO2(g), ΔH° = 66.4 kJ/mol and ΔS° = -121.5 J/K. Is there a temperature at which the spontaneity of this reaction be changed, either from spontaneous to nonspontaneous or nonspontaneous to spontaneous? If so, estimate the temperature.

Question 2

Acetylene, C2H2, has a standard enthalpy of formation, ΔH° = 226.7 kJ/mol, and a standard entropy change for its formation from its elements, ΔS° = 58.8 J/K∙mol. The standard free energy of formation of acetylene is ________ kJ/mol.
