Consider the following table :
$\displaystyle a$ and $\displaystyle b$ are van der Waals constants. The correct statement about the gases is :
| Gas | $\displaystyle \mathrm{a} /\left(\mathrm{k} \mathrm{Pa} \mathrm{dm}^6 \mathrm{~mol}^{-1}\right)$ | $\displaystyle \mathrm{b} /\left(\mathrm{dm}^3 \mathrm{~mol}^{-1}\right)$ |
| A | $\displaystyle 642.32$ | $\displaystyle 0.05196$ |
| B | $\displaystyle 155.21$ | $\displaystyle 0.04136$ |
| C | $\displaystyle 431.91$ | $\displaystyle 0.05196$ |
| D | $\displaystyle 155.21$ | $\displaystyle 0.4382$ |
