Q. No.
Given below are two statements:
Assertion  (A): When an ideal binary solution is in equilibrium with its vapour, the molar ratio of the two components in the solution and in the vapour phase may or may not be the same.
Reason (R): The vapour pressure of a solution depends upon the vapour pressures of volatile components.
 
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.

Hints
Assertion(A): If a liquid solute more volatile than the solvent is added to the solution, the vapour pressure of the solution is greater than the vapour pressure of the pure solvent.
Reason(R): Vapour pressure of the solution is equal to the vapour pressure of the solvent.

1. Both A and R are correct and R is the correct explanation of A.
2. Both A and R are correct but R is not the correct explanation of A.
3. A is true and R is false.
4. A is false and R is true.

Given below are statements:
Assertion (A): Henry's law states that “the partial pressure of the gas in vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution”.
Reason (R): Raoult's law is a special case of Henry's law.
 
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True, but (R) is False.
4. (A) is False, but (R) is True.
