An Intiative by Sri Chaitanya

Relative lowering of vapour pressure of a solution of non-volatile solute is equal to mole fraction of solute in the solution.

Lowering of vapour pressure of solution of non-volatile solute is directly proportional to mole fraction of solute in the solution.

Detailed Solution

(1) p0-pp0 = X2− Raoult's LawWhere X2 = M.F of solute(2)p0−pp0 = X2 p0−p = p0 X2 ∴ p0−p ∝ X2(2) is correct.(3)pS= p0 X1 pS α X1 (3) is correct.(4) RLVP is equal to X2 , independent of temperature
