A reaction with a positive enthalpy change (ΔH = 62.4 kJ/mol) indicates that it is endothermic, meaning it absorbs heat from the surroundings. The positive entropy change (ΔS = 0.145 kJ/K) suggests an increase in disorder or randomness in the system. To determine the spontaneity of the reaction at a given temperature, the Gibbs free energy change (ΔG) can be calculated using the equation ΔG = ΔH - TΔS; if ΔG is negative, the reaction is spontaneous. At higher temperatures, the positive ΔS could favor spontaneity despite the endothermic nature.
