  • D
    Forces of attraction between the gas molecules
✓

Answer

Correct option: C.
Forces of attraction between the gas molecules
The correction factor $'a\ '$ to the ideal gas equation corresponds to forces of attraction between the gas molecules. Greater the value of $'a\ ',$ more easily a gas can be liquefied. The unit of $'a\ '$ is at $\text{mL}^2 \ce{ mol}^{-2}$.
