A small sample of an organic compound (a nonelectrolyte) was added to benzene (Freezing point = 5.5°C)
and lowered its freezing point. The molality of the mixture was 0.613 m. Kę for benzene = 5.12 °C/m). What
was the new freezing point?
O 5.5°C
2.4°C
O 3.1°C
8.6°C
none of these

The new lowered freezing point of the benzene mixture is determined as 2.4°C.

Effect of impurities in freezing point

The presence of impurities lowers the vapour pressure of the solution since the concentration of the solution is increased.

Change in temperature of the new mixture = 0.613 x 5.5°C = 3.1 °C

New freezing point = 5.5°C - 3.1°C = 2.4°C

Thus, the new lowered freezing point of the benzene mixture is determined as 2.4°C.
