Problem:The definition of the acentric factor includes the negative log of the reduced form of this quantity, when the reduced temperature is 0.7. A pure liquid's fugacity is approximated as the product of the fugacity coefficient, the Poynting factor, and this quantity. This quantity is not unitless, but it is smaller for the heavy key component during separations. The logarithm of this quantity varies linearly with one over temperature by (*) Antoine's equation. At high concentrations, a component's partial pressure equals its mole fraction times this quantity according to Raoult's Law. It equals atmospheric pressure at the boiling point. For 10 points, name this quantity, the pressure of gas above a solution.
Solution:
