319433 Choose the correct statement with respect to the vapour pressure of a liquid among the following :-

1 Increase linearly with increasing temperature
2 Decrease non-linearly with increasing temperature
3 Decrease linearly with increasing temperature
4 Increase non-linearly with increasing temperature
CHXII02:SOLUTIONS

319434 Assertion :
The pressure exerted by the vapour over the surface of the liquid at the equilibrium at a given temperature is called the vapour pressure of the liquid.
Reason :
If a non-volatile solute is added to a solvent to give a solution, the vapour pressure of the solution is found to be greater than the vapour pressure of the pure solvent.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.

319435 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 were placed in closed containers of same material and same capactiy as shown in figure:
