Question

The following data is obtained for one mole of a gas. The gas deviates from ideal behavior in the pressure (in bar) range

• A. 1 to 3
• B. 2 to 4
• C. 3.1 to 4.0
• D. 1 to 4

Hint:

Ideal gas behavior is assumed when the PV/RT ratio is constant. Deviations occur when the gas interacts significantly, such as at high pressures.

Answer 1

The Correct Option is C

In the given data, the gas starts to deviate from ideal behavior at P = 3.1 bar and continues to deviate until P = 4.0 bar. The PV/RT values indicate ideal behavior up to P = 3.0 bar, but deviations are observed after that, starting from P = 3.1 bar.
