`p^@` and `p` are vapour pressure of pure liquid and solution respectively. Among (a) `p^@,` (b) `p//p^@` and (c) `(p^@ - p)//p^@`, which are temperature independent. Why ?

Text Solution

Verified by Experts

`p//p^@` and `(p^@-p)//p^@` are temperature independent. `p//p^@` is mole fraction of solvent and `(p^@-p)//p^@` is mole fraction of solute.
Mole-fraction of a component is not dependent on temperature.
