In the following compressibility factor (Z ) vs pressure graph at K 300 , the compressibility of `CH_4` at pressure 200  bar deviates from ideal behaviour because

A

The molar volume of `CH_4` is less than its molar volume in the ideal state

B

The molar volume of `CH_4` is same as that in its ideal state

C

Intermolecular interactions between`CH_4` molecules decreases

D

The molar volume of `CH_4` is more than its molar volume in the ideal state

Text Solution

Verified by Experts

The correct Answer is:
A
`Z = ((V_M)_r)/((V_M)_i) lt 1` at P < 200 bar
`therefore (V_M)_r lt (V_M)_i`
