If a reaction has a ΔG of - 136kJ at 110°C, will it be spontaneous at this temperature (110°C) ?

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.
