Problem

The pressure exerted by 1 mole of

\text{CO}_2

273 \text{ K}

, is

34.98 \text{ atm}

. Assuming that volume occupied by

\text{CO}_2

molecules is negligible, the value of van der Waals' constant for attraction of

\text{CO}_2

gas is : a.

3.59 \text{ dm}^6 \text{ atm mol}^{-2}

2.59 \text{ dm}^6 \text{ atm mol}^{-2}

1.25 \text{ dm}^6 \text{ atm mol}^{-2}

1.59 \text{ dm}^6 \text{ atm mol}^{-2}
