Explain the elevation in boiling point of solution.

Explanation

*When a non-volatile solute is added to solvent vapoure pressure of a solution decreases.
* This solution has higher boiling point than the boiling point of solvent.
* For a dilute solution elevation in boiling point `(DeltaT_(b))` is directly proportional to the molal concentration of the solute in a solution.
`DeltaT_(f)=m,DeltaT_(b)=K_(b)m`
`DeltaT_(b):`is elevation in boiling point i.e., `DeltaT_(b)=T_(b)-T_(b)^(0)`
`T_(b),`is boiling point of solution `T_(b)^(0):` is boiling point of pure solvent
`K_(P):` is molal elevation constant m:is molality of a solution.
