This comment concerns the contribution of configurational mixing entropy to the change in the total Gibbs free energy in the process of vacancy formation and the consequent effect on the thermal equilibrium vacancy concentration in multicomponent alloys. A different derivation is shown than that in [Phys. Rev. B 93, 134115 (2016)], correcting an error that may come from using Gibbs free-energy per site. The derivation is further generalized to systems beyond binary alloys.
