In three beakers labeled as (1), (2) and (3), 100 mL, of water, 100 mL of 1 M solution of glucose in water are taken respectively and kept at same temperature.
Which of the following statement is correct
Vapour pressure in all the three beakers is same.
Vapour pressure of beaker B is highest.
Vapour pressure of beaker C is higher.
Vapour pressure of beaker B is lower than that of C and vapour pressure of beaker C is lower than that of A.
Vapour pressure of beaker B is lower than that of C and vapour pressure of beaker C is lower than that of A.
Solution
Vapour pressure of a solution containing non volatile solute is less than that of the pure solvent. The decrease in vapour pressure depends upon the quantity of non volatile solute present in it. Hence, vapour pressure of A > C > B
