Two beakers of capacity 500 mL were taken. One of these beakers, labelled as "A" was filled with 400 mL water whereas the beaker labelled "B" was filled with 400 mL of 2M solution of NaCl. At the same temperature both the beakers ware placed in containers os same material and same capacity as shown in figure.

A

Vapour pressure in container (A) is more than that is container (B)

B

Vapour pressure in container (A) is less than that is container (B)

C

Vapour pressure is equal in both the containers .

D

Vapour pressure in container (B) is twice the vapour pressure in container (A)

Text Solution

Verified by Experts

The correct Answer is:
A
When a non-volatile solute (NaCl) is dissolved in a liquid , its vapour pressure decreases.
