Chemical Engineering Thermodynamics A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is Φi yi P = Yi xi fi° where, Φ is a vapor fugacity component, Yi is the liquid activity co-efficient and fi° is the fugacity of the pure component i. the Ki value (Yi = Ki xi) is therefore, in general a function of Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi Temperature only Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi Temperature only ANSWER DOWNLOAD EXAMIANS APP
