Vedclass · Answer

(C) The deviation from ideal behaviour is expressed by the compressibility factor $Z.$ $Z$ is defined as $Z = \frac{PV}{nRT}.$ For an ideal gas,$PV = nRT,$ so $Z = 1.$ When $Z > 1,$ the gas shows positive deviation from ideal behaviour. This implies that the gas is less compressible than an ideal gas,meaning real gases are difficult to compress compared to ideal gases.

Consider the equation $Z = \frac{PV}{RT}.$ Which of the following statements is correct?
