Solution

The correct option is A $Z > 1$

From the above figure, it can be seen that above Boyle's temperature real gases show positive deviation and below Boyle's temperature real gases show negative deviation.

Hence, the correct answer is option $A$ .

Q. The sketch shows the plot of Z vs P for 1 mole of a hypothetical gas at three distinct
temperatures:

Boyle's temperature is the temperature at which a gas shows ideal behaviour over a
pressure range in the low pressure region. Boyle's temperature

(T_{b}) = \frac{a}{R b}

. If a plot is
obtained at temperatures well below Boyle's temperature, then the curve will show a negative deviation in the low pressure region and a positive deviation in the high pressure
region.

In the first figure, in the plot at

500 K, Z

changes from 2 to 2.2 as the pressure varies from 1000 atm to

1200 atm

(high pressure). The value of
