The equation for calculating the change in free energy (ΔG) is:
ΔG = ΔH - TΔS

At the point where the reaction reaches equilibrium (ΔG = 0), we can rearrange the equation to solve for the temperature (T):
T = ΔH/ΔS

Plugging in the values given for ΔH and ΔS, we get:
T = (-19.9 kJ/mol) / (-55.5 J/K-mol)
T = 359 K

Therefore, the answer is A) 359.
