Vapour pressure is the pressure exerted by vapours

Vapour pressure is measured in –

Vapour pressure of a solution is

The vapour pressure is least for

The vapour pressure is least for

Mole fraction of component A in vapour phase is chi_(1) and that of component A in liquid mixture is chi_2 , then ( p_(A)^@ )= vapour pressure of pure A, p_(B)^@ = vapour pressure of pure B), the total vapour pressure of liquid mixture is
