Above figure represents Vapour pressure versus Temperature graphs of 2 pure volatile liquids and a solution formed by the 2 liquids.
(i) Which curve represents the solution?
(ii) Which curve represents the liquid with the strongest intermolecular forces of attraction?
- A (i) B (ii) A
- B (i) A (ii) C
- C (i) C (ii) A
- D (i) B (ii) C
Answer & Solution
Correct Answer
(D) (i) B (ii) C
Step-by-step Solution
Detailed explanation
The vapour pressure of a solution containing two volatile liquids is always intermediate between the vapour pressures of the two pure components at a given temperature. In the graph, curve A represents the liquid with the highest vapour pressure (weakest intermolecular forces),…
