Question

The Compressibility factor Z=(PV/nRT) of gas above T= a/Rb will be:​

Answer 1

Given : The compressibility factor Z = (PV/nRT) of a gas above T = a/Rb will be

1. less than unity
2. greater than unity
3. equal to unity
4. equal to zero

solution : we know, T = a/Rb is known as Boyle's Temperature. The temperature at which a real gas behaves like an ideal, is known as Boyle's temperature.

Above the Boyle's temperature, gas is less compressible than ideal behaviour. it means compressibility factor of gas is higher than that of ideal gas.

we know, compressibility factor of an ideal gas, Z = 1

so, compressibility factor of gas is greater than 1 or unity.

Therefore option (2) greater than unity, is correct choice.
