Answer:
Units of a = 
Units of b = 
Explanation:
The Van der Waal's equation is:-

Where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value
a and b are van der Waal's constant
If pressure is taken in atm and volume in L. So,
represents the pressure correction term. Then,
Units of a = 
represents the volume correction term. Then,
Units of b =
