Question

In van der Waals equation of state for a non-ideal gas, the term that accounts for intermolecular forces is

(a) (V - b)

(b) (RT)^-1 

(c) (P + a/V²)

(d) RT

Answer 1

The correct option is : (c) (P + a/V²)

Explanation:

van der Waal's equation for 1 mole is 

Here, (P + a/V²) represents the intermolecular forces and (V - b) is the corrected volume.
