Answer:
The answer to your question is Yes, it is spontaneous
Explanation:
Gibbs free energy is the sum of the enthalpy plus the product of the temperature and the entropy of the system.
G = H - TS
The sign of the Gibbs free energy of a reaction determines if the reaction is spontaneous or nonspontaneous.
If ΔG > 0 the reaction is non-spontaneous
If ΔG < 0 the reaction is spontaneous
In this question ΔG = -136 kJ, then it will be spontaneous.
