Consider a binary liquid mixture at constant temperature 
and pressure 
. If the enthalpy change of mixing, 
, where 
and 
are the mole fraction of species 1 and 2 respectively, and the entropy change of mixing 
(with 
), then the minimum value of the Gibbs free energy change of mixing at 300 K occurs when
