Is it justified to compare the free energy change of two reactions and conclude one is more favourable than the other?

Suppose we consider the binding of a ligand L to a metal M, M+L=ML and M+2L=ML2 . We compute the Gibbs free energy change for two reaction using DFT. But can we compare this two free energies to...
