A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is φi yi P = Yi xifi° where, Φ is a vapor fugacity component, Yi is the liquid activity coefficient and fi° is the fugacity of the pure component i. the Ki value (Yi = Ki xi) is therefore, in general a function of ______________________?
Correct answer: C
Explanation
The K value relates fugacities and activity coefficients, which depend on temperature, pressure, and the liquid composition (xi).
