Question
The given graph represents the variation of Z(compressibility factor 
) versus P, for three real gases A, B and C. Identify the only incorrect statement.
) versus P, for three real gases A, B and C. Identify the only incorrect statement. Options
A.For the gas A, a = 0 and its dependence on P is linear at all pressure.
B.For the gas B, b = 0 and its dependence on P is linear at all pressure.
C.For the gas C, which is typical real gas for which neither a nor b = 0. By knowing the minima and the point of intersection, with Z = 1, a and b can be calculated.
D.At high pressure, the slope is positive for all real gases.
