82.1 Solubility at equilibrium~平衡溶解度 For example Fig 8-4, p=1013kpa, t=40C, all points of(ye,xe) on the curve pertain to(关于) the same temperature and pressure. 2 Factors affecting on solubility According to the phase rule. F=3 In the four variables of T, P, pa and cA, there are three independent variables only where: pa partial pressure of A in gas phase. CA =f(T,P,pAFor example Fig .8-4， p=101.3kpa，t=40℃, all points of (ye , xe ) on the curve pertain to (关于）the same temperature and pressure. 2 Factors affecting on solubility ∵ According to the phase rule, F =3 ∴ In the four variables of T, P, pA and cA, there are three independent variables only. where: pA ～ partial pressure of A in gas phase. 8.2.1Solubility at equilibrium ～平衡溶解度 ( A ) * C = f T, P,p A
