Question

For a dilute solution, Raouh's law states that  

(a) the lowering of vapour pressure is equal to the mole fraction of solute 

(b) the relative lowering of vapour pressure is equal to the " mole fraction of solute 

(c) the relative lowering of vapour pressure is proportional - to the amount of solute in solution 

(d) the vapour pressure of the solution is equal to the mole fraction of solvent 

Answer 1

The correct option (b) the relative lowering of vapour pressure is equal to the mole fraction of solute

Explanation:

According to Raoult's law, "the relative lowering of vapour pressure is equal to the mole fraction of solute' '.
