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 only Temperature, pressure, liquid composition xi and vapour composition yi Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature only Temperature, pressure, liquid composition xi and vapour composition yi Temperature, pressure and liquid composition xi only Temperature and pressure only ANSWER DOWNLOAD EXAMIANS APP
