This equation is used to calculate the pure component of isosteric heat of adsorption. In metamorphism, dehydration and decarbonation reactions are two cases in which this equation yields non-linear results due to changes in volume. Under ideal assumptions, a quantity in this equation simplifies to RT over P; that simplified form (-5[1])of this equation can be used to calculate (-5[1])rotovap thresholds. Replacing vapor pressure in this equation with the equilibrium constant gives the van't Hoff equation. (10[3]-5[1])In this equation, (10[1])specific latent heat is held constant and is divided by temperature and specific volume. Metastable states caused by superheating or supercooling can be represented by extending this equation's calculations beyond the triple point. (-5[1])For 10 points, name this equation used to find the slopes of coexistence curves on phase diagrams. ■END■ (10[3]0[3])
