Let measured volume of gas = V
Volume occupied by gas molecules = b
Thus, Correct Volume of gas = V - b
Let pressure exerted on the gas = P
Force of attraction among the molecules which decreases the pressure of the gas = a/v^2
Thus, Correct pressure of the gas = P + a/v^2
Hence, using correct pressure and volume in the ideal gas equation, we have
(P + a/v^2) (V - b) = RT
THIS IS VENDARWAAL EQUATION FOR 1 MOLE OF A GAS.
FOR n MOLE OF GAS the equation will be-
(P + a/v^2) (V - b) = RT
Volume occupied by gas molecules = b
Thus, Correct Volume of gas = V - b
