The temperature at which the given reaction is spontaneous needs to be determined. Concept Introduction: The change in enthalpy and change in entropy of a reaction can be calculated using the change in enthalpy of formation and entropy of components respectively from the thermodynamic table (at 298 K). These two values do not depend on T thus, the value will be the same for all the temperature values. Here, the change in Gibbs free energy of reaction changes with T thus, it is calculated as follows: Δ G = Δ H − T Δ S Here, Δ H is the change in enthalpy, Δ S is the change in entropy, and T is temperature.
