A mole of CCl4 vapours at 77∘ C occupies a volume of 36.0 L.If vanderwaals constants are a=20.39L2 atm mol−2 and b=0.1383 L mol−1 calculate the compressibility factor Z under (a) low pressure region and (b) high pressure region.
The values of compressibility factor Za and Zb respectively are:
Za = 0.82, Zb = 1.12
Za= 0.98, Zb =1.004
The compressibility factor for an ideal gas is:
The compressibility factor for an ideal gas is
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
For gas B, b=0 and its dependence on p are linear at all pressures.
For the gas C, which is typical real gas which neither a 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.
For gas A, a=0 and its dependence on p is linear at all pressures.
