The reaction involves the conversion of liquids to gases, which increases the disorder in the system, indicating a positive change in entropy (ΔS > 0). Given that the reaction is exothermic (ΔH < 0) and increases disorder, it is likely to be spontaneous at standard conditions, suggesting a negative change in free energy (ΔG < 0).
