Question

1.22 gm C₆H₅COOH is added into two solvents, and the data for $Δ T_{b}$ and $K_{b}$ are given as:

(1) In 100 gm CH₃COCH₃: $Δ T_{b} = 0.17$ K, $K_{b} = 1.7 (\frac{Ke l v in - K g}{m o l})$

(2) In 100 gm benzene: $Δ T_{b} = 0.13$ K, $K_{b} = 2.6 (\frac{Ke l v in - K g}{m o l})$

Which of the following is/are correct?
