Suppose that at a pressure of 1 atm and temperature 300 K, a given material has two possible phases: liquid (L) and solid (S). We start the system with Nliquid = 5 moles in the liquid phase and Nsolid = 9 moles in the solid phase. For these values of pressure and temperature, Hliquid = 5 x 10⁻²¹ J and Hsolid=9 x 10⁻21 J. What is the equilibrium value of Nliquid?
a. 9 mol
b. 14 mol
c. 1.49 mol
d. 5 mol
