How is relative lowering of vapour press...

How is relative lowering of vapour pressure defined for a solution consisting of volatile solvent and non-volatile solute ? How is this function related to the mole fraction of the solvent and of the solute?

Text Solution

Verified by Experts

The correct Answer is:
Relative lowering of vapour pressure is equal to mole fraction of solute if solute is non-volatile and only solvent is volatile.
