Question

Define Raoult’s law for the elevation of the boiling point of a solution.

Answer 1

The elevation in boiling point of a solution is directly proportional to the molal concentration (molality) of the solute in the solution.

ΔT_b = K_b m

Where

ΔT_b = Elevation in boiling point

K_b = Molal elevation constant (ebullioscopic constant)

m = Molality of the solution
