Question : 57 of 120

Marks: +1, -0

The given graph represents the variation of Z (compressibility factor = PV /nRT ) versus P, for three real gases A, B and C. Identify the only incorrect statement.

[JEE Adv 2006 P1]

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 = 0 nor b = 0. By knowing the minima and the point of intersection, with Z = 1, a and b can be calculated.
At high pressure, the slope is positive for all real gases.
