In the depression of freezing point experiment
A. Vapour pressure of the solution is less than that of pure solvent
B. Vapour pressure of the solution is more than that of pure solvent
C. Only solute molecules solidify at the freezing point
D. Only solvent molecules solidify at the freezing point
Choose the correct answer from the options given below:
- a✓
A and D only
- b
B and C only
- c
A and C only
- d
A only
A and D only
Strategy:\n> For the same solvent ( constant), the elevation is proportional to the number of particles ().\n\nStep 1: Calculate effective particles\nSolute X is a non-electrolyte ().\n- .\n- is proportional to 0.02.\n\nStep 2: Compare to glucose\nGlucose is a non-electrolyte (). Molar mass = 180.\n- .\n- Elevation for X will be much greater.\n\n
