1 mole of a diatomic gas present in a 10 L vessel at a certain temperature exerts a pressure of 0.96 atm. Under similar conditions, an ideal gas exerts 1.0 atm pressure. If the volume of a gas molecule is negligible, then find the value of the van der Waals’ constant ‘a′ (in atm L2/mol2).
'b' is negligible ∴(P+aV2m)Vm=RT
Now, Vm=10 L
