Relative volatility varies with the concentration of component for an ideal solution. The relative volatility of a binary mixture may be defined as the ratio of vapor pressure of component ‘A’ to that of component ‘B’, when_________________?

Question

Accepted Answer

Vapor phase obeys Dalton’s law and liquid phase obeys Raoult’s law. Relative volatility is defined when the liquid phase follows Raoult's law and the vapor phase follows Dalton's law.
