Enthalpy minus the product of entropy and temperature is the formula for one of this man's quantities, the change in which is negative for spontaneous reactions.
This scientist introduced the idea of a statistical ensemble to create a system that considers all possible microstates. This man names an equation that relates changes in chemical potential for a thermodynamical system with Duhem, while he also proposed that the number of degrees of freedom is equal to the number of components minus the number of phases plus two in his namesake (*) phase rule. Enthalpy minus the product of entropy and temperature is the formula for one of this man's quantities, the change in which is negative for spontaneous reactions. For ten points, name this American scientist who names a type of free energy symbolized G.
