For an van der Waals' gas, the term `((ab)/(V^(2)))` represents some

A

pressure

B

energy

C

critical density

D

molar mass

Text Solution

Verified by Experts

For `(ab)/(V^(2))` a and b are vader Waals. constants
Unit of `a=("atm". L^(2))/(("mole")^(2))` Unit of b `=L/("mole")`
V=volume of gas per mole =L/mole
So `(ab)/(V^(2))=(("atm".L^(2))/(("mole")^(2))xxL/("mole"))/((L//"mole")^(2))=("atm"L)/("mole")`
it is the unit of energy.
