If \\chi_{1} and \\chi_{2} represent the mole fractions of a component A in the vapour phase and liquid mixture respectively, and p^\circ_{A} and p^\circ_{B} represent vapour pressures of pure A and pure B, then total vapour pressure of liquid mixture is

{p^\circ_{A} \\chi_{1}}/{\\chi_{2}}

{p^\circ_{A} \\chi_{2}}/{\\chi_{1}}

{p^\circ_{B} \\chi_{1}}/{\\chi_{2}}

{p^\circ_{B} \\chi_{2}}/{\\chi_{1}}
