(Q.)  Calculate the pressure exerted by 1 mol of COat 273 K if the van der Waal’s constant ‘a’= 3.592 dm6atm mol-. Assume that the volume occupied by CO2 molecules is negligible.

Hi Vaishnavi,
The answer to your question is as follows.
According to van der Waals equation of state for 1 mole of a gas,
(P + a/V2)(V- b) = 0
Since, the volume occupied by CO2 molecules is negligible, b = 0.
Hope, you got the answer.
Best wishes!
