Explain vapour liquid equilibrium (VLE).
An activity coefficient is a factor used in thermodynamics to account for deviations from ideal behaviour in a mixture of chemical substances. In an ideal mixture, the microscopic interactions between each pair of chemical species are the same (or macroscopically equivalent, the enthalpy change of solution and volume variation in mixing is zero) and, as a result, properties of the mixtures can be expressed directly in terms of simple concentrations or partial pressures of the substances present e.g. Raoult's law. Deviations from ideality are accommodated by modifying the concentration by an activity coefficient. Analogously, expressions involving gases can be adjusted for non-ideality by scaling partial pressures by a fugacity coefficient.
How to Calculate Liquid phase mole fraction using Gamma - phi formulation of VLE?
Liquid phase mole fraction using Gamma - phi formulation of VLE calculator uses Mole Fraction of Component in Liquid Phase = (Mole Fraction of Component in Vapor Phase*Fugacity Coefficient*Total Pressure)/(Activity Coefficient*Saturated Pressure) to calculate the Mole Fraction of Component in Liquid Phase, The Liquid phase mole fraction using Gamma - phi formulation of VLE formula is defined as the ratio of the product of the vapour phase mole fraction, the fugacity coefficient and the total pressure to the product of the activity coefficient and the saturated pressure of mixture or solution. Mole Fraction of Component in Liquid Phase is denoted by xLiquid symbol.
