Relative lowering of vapour pressure |
|
Answer» Solution :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. |
