5 The given graph represent the variations compressibility factor Z versus p for three real pV nRT gases A B and C Identify the only incorrect statement 2006 5M nive explanation 1 Z C A B A Ideal gas B C 0 p atm 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
