What types of experiments can be carried out to determine whether a reaction is spontaneous? Give two examples each of spontaneous and non-spontaneous processes.

Question: What types of experiments can be carried out to determine whether a reaction is spontaneous? Give two examples each of spontaneous and non-spontaneous processes.
Answer:
The Gibbs free energy can be determining to check the reaction is spontaneous or not. Gibbs free energy is essentially available energy to do work, denoted by 'ΔG.'
According to Gibbs free energy,
ΔG = ΔH - TΔS
Where ΔH is Enthalpy of reaction, ΔS is the Entropy of the reaction, and T is the Temperature in Kelvin.
Case1: If ΔG◦ <0, then...
