Question

At 35°C, the vapour pressure of , is 512 mm Hg and that of acetone is 144 mmHg. A solution of  in acetone has a total vapour pressure of 600 mmHg. The false statement amongst the following is:

Canvas Classes · Accepted Answer

Strategy:
 Compare the actual measured total pressure (600 mm Hg) with the individual pure vapour pressures (144 and 512 mm Hg). If the total pressure exceeds the highest individual pressure, the system shows extreme positive deviation from Raoult's Law.

Step 1: Identify the deviation type
The total pressure (600) is greater than both  (512) and  (144).
This indicates positive deviation.

Step 2: Evaluate statement (2)
"The volume of a mixture... has a volume < 200 mL".
In systems with positive
