Ebullioscopic constant `K_(b)` corresponds to the change in boiling point produced by a one ___ ideal solution of a nonvolatile nonelectrilyte.

Options

A. molar
B. molal
C. normal
D. formal

Answer

2

Explanation

The elevation of nonvolatile point produced by dissolving `1 mol` of any nonvolatile solute, which does not dissociate or associate, in `1 kg` of a particular solvent is known as the ebillioscopic constant for that solvent. It is the ratio of the elevation in `BP` to molality, i.e., `K_(b)=DeltaT_(b)//m`
Thus, the units of `K_(b)` are `.^(@)C//m` or `K//m` or `KKg mol^(-1)`.
