Vedclass · Answer

(C) The Van der Waals equation for one mole of a real gas is given by $\left( P + \frac{a}{V^2} \right)(V - b) = RT$.In this equation,the term $\frac{a}{V^2}$ is the pressure correction term,which accounts for the intermolecular attractive forces (adhesive forces) between gas molecules.The term $b$ is the volume correction term,which accounts for the excluded volume due to the finite size of the gas molecules.Therefore,$a$ represents the intermolecular attractive force,and $b$ represents the correction in volume.Correct choice - $C$.

In Van der Waals equation $\left( P + \frac{a}{V^2} \right)(V - b) = RT$,what do $a$ and $b$ represent?
