Question

The given graph represents the variation of $Z$ (compressibility factor $= \frac{P V}{n RT}$ ) versus $P$ , for three real gases $A, B$ and $C$ .

Identify the only incorrect statement :

For the gas

A

a = 0

and its dependence on P is linear at all pressures

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
