Answer:
359 K
Explanation:
The Gibbs free energy can be calculated using the following expression.
ΔG = ΔH - T.ΔS
where,
ΔG is the Gibbs free energy
ΔH is the enthalpy of the reaction
T is the absolute temperature
ΔS is the entropy of the reaction.
When ΔG = 0,
ΔH - T.ΔS = 0
ΔH = T.ΔS
T = ΔH/ΔS = (-19.9 × 10³ J/mol) / (-55.5 J/K.mol) = 359 K
