Formation constant and Gibbs free energy For the complex formation reaction where Mis any metal and L is any ligand, M+ + 2L = [ML2]* Kr is the formation constant for the complex at equilibrium and AG is the Gibbs free energy change for the reaction at equilibrium. The formation constant (K) can be related to the Gibbs free energy change (AG°) for a reaction by the equation AG° = RT In Kr where T is the temperature in kelvins and R is the gas constant equal to 8.314 J K. mol. The complex formation is generally a spontaneous process; thus, the Gibbs free energy change is negative.
