Question

A sample of air is saturated with benzene (vapour pressure = 100 mmHg at 298 K) at 298 K, 750 mmHg pressure. If it is isothermally compressed to one third of its initial volume, the final pressure of the system is (A) 2250 torr (B) 2150 torr (C) 2050 torr (D) 1950 torr

Fixed P=100+3 × (750-100) =2050 for the system

Q. A sample of air is saturated with benzene (vapour pressure $= 100 mm H g$ at $298 K)$ at $298 K$ , $750 mm H g$ pressure. If it is isothermally compressed to one third of its initial volume, the final pressure of the system is

2250 torr

2150 torr

2050 torr

1950 torr

Fixed $P = 100 + 3 \times (750 - 100)$
$= 2050$ for the system
