The given graph in Fig represents the variation of Z (compressibility factor=pVnRT) vs.P , for the three real gases A,B and C.identify the only incorrect statement
1−pbRT
For the gas C, which is typical real gas which neither a nor b=0.By konowing the minima and the point of intersection with z=1,a and b can be calculated.
B relates to the incompressible volume of the molecules and measures the effective size of gas molecules.
Z=pVRT=1 for an ideal gas.
Note : options (A) , (B) and (D) are well established Eliminating the right statements,
option C is the required Answer C must be incorrect
