Relative lowering of vapour pressure
- Vapour pressure of a solvent present insolution is less than the vapour pressure of the pure solvent.
- According to Raoult lowering of vapour pressure of a solution depends only on the concentration of thesolute particles and remains independent of their identity.
- p1 =x1 p10
- The reduction in the vapour pressure of solvent (p1) is given as:
Δp1 = p10 - p1 = p10 - p10x1
= p10 (1-x1)
As x2=1-x1 the above equation reduces to Δp1= x2p10
