Assertion (A): | When an ideal binary solution is in equilibrium with its vapour, molar ratio of the two components in the solution and in the vapour phase may or may not be the same. |
Reason (R): | Vapour pressure of 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. |
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. |
