Question

In the following compressibility factor $\left(Z\right)$ vs. pressure graph at $300K$, the compressibility of $C{H}_4$ at pressure $<200$ bar deviates from ideal behaviour because

• A. The molar volume of $C{H}_4$ is less than its molar volume in the ideal state
• B. The molar volume of $C{H}_4$ is same as that in its ideal state
• C. Intermolecular interactions between $C{H}_4$ molecules decreases
• D. The molar volume of $C{H}_4$ is more than its molar volume in the ideal state
