Relative lowering of vapour pressure

Text Solution

Verified by Experts

Relative lowering of vapour pressure : If `P_(0)` and P are the respective vapour pressures of a pure liquid (solvent) and the solution containing a nonovolatile solute then `P lt P_(0)`. Hence, `P_(0)-P` represents the lowering of the vapour pressure due to addition of a nonvolatile solute.
`therefore` Relative lowering of vapour pressure.
