WebAll steps. Final answer. Step 1/5. 1. To determine whether the reaction is spontaneous or nonspontaneous, we can calculate the standard Gibbs free energy change using the following equation: ΔG˚ = ΔH˚ - TΔS˚ where ΔH˚ is the standard enthalpy change, ΔS˚ is the standard entropy change, and T is the temperature in Kelvin. WebGibbs free energy is equal to the enthalpy of the system minus the product of the temperature and entropy. G = H – TS Where, G is the Gibbs free energy H is enthalpy T is temperature S is entropy Gibbs free energy is a state function. The change in Gibbs free energy formula is given below: ΔG = ΔH - T * ΔS
