At which temperature would a reaction with AH = -220 kJ/mol and
AS=-0.05 kJ/(mol-K) be spontaneous?

Explanation:

The condition for a reaction to be spontaneous is that the change if the free energy, ΔG, be negative.

The definition of G is G = H - TS, from which, at constant temperature:

Thus, you must solve:

Substituting:

The only choice with a temperature less than 4,400K is C. 3600K.
