Solutions

1 g of a non-volatile non – electrolyte solute is dissolved in 100 g of two different solvents A and B whose ebulliscopic constants are in the ratio of 1:5. The ratio of the elevation in their boiling points, $\frac{∆{\mathrm{T}}_{\mathrm{b}}\left(\mathrm{A}\right)}{∆{\mathrm{T}}_{\mathrm{b}}\left(\mathrm{B}\right)}$ is:

• 1:0.2

• 10: 1

• 5: 1

• 1: 5
