Question 4: Palette 4/6

BITSAT 2022 MCQ

The given graph represents the variation of compressibility factor (Z) = $\frac{pV}{nRT}$, for three real gases A, B and C. Identify the only incorrect statement.

BITSAT 2022 Chemistry - States of Matter Question 4 English

For the gas A, a = 0 and its dependence on p is linear at all pressure.

For the gas B, b = 0 and its dependence on p is linear at all pressure.

For the gas C, which is typical real gas for which neither a nor b = 0. By knowing the minima and point of the intersection with Z = 1, a and b can be calculated.

At high pressure the slope is positive for all real gases.
