Two phase (α and β) of a species are in equilibrium. The correct relations observed among the variables, T, p and μ are:

The equilibrium constant of a reaction becomes doubled on raising the temperature from 25°C to 35°C. Calculate ΔH° for the reaction.

Determine the pressure of CO₂ gas at 700 K in the heterogeneous equilibrium reaction CaCO₃(s) CaO(s) + CO₂(g) if ΔG° for this reaction is 130.2 kJ mol^–1.

­­­­­­­­­­­­­At 100° C, the specific volumes of water and steam are, respectively 1 c.c. and 1673 c.c. respectively. Determine the change in vapor pressure (in mm Hg) of the system by 1°C change in temperature. The molar heat of vaporization of water in this range may be taken as 40584.8 J mol^-1.

The temperature at which a compound melts into a liquid of the same composition as the solid is called the
