Question

|Show that the relative lowering of vapour pressure for a solution is equal to the mole fraction of the solute when solvent alone is volatile

Answer 1

For a solution of volatile liquids Raoult’s law, is given as

P = PA + PB

If solute (component B) is non-volatile then

Thus, relative lowering of vapour pressure is equal to the mole fraction of non-volatile solute.

I hope this will help you
