# what is the unit of the constants in van der waal's equation?plzzzzzzzzz answer as soon as possible

The Van der Waal's equation is given as follows

where p is the pressure of the gas, V is the volume, n are the number of moles of the gas, T is the temperature and R is the universal gas constant. The constant 'a' is a measure of the magnitude of attractive forces between the molecules of a gas. Its unit is atm L2mol−2or bar L2mol−2. Larger the value of ‘a’, larger will be the intermolecular force of attraction. It is independent of pressure and temperature. The constant 'b'  is a measure of the effective size of gas molecules. Its unit is L mol−1.

(p+a/v2)(v-b)

p=pressure

v=volume

t=temperature

r=gas constant

find a and b

i'm leaving the solving part to you as you've only asked the question.
