The following expression of P - V work done W=-∫ P text ext d V is applicable for reversible isobaric as well as isothermal and adiabatic process. If P text /ext is substituted for a Vander Waals equation then it becomes W=-∫((R T/V-b)-(a/V2)) d V But it is not applicable for irreversible process which are carried out very fast. So work done is calculated assuming final pressure remains constant throughout the process

Q. In thermodynamics, the P−V work done is given by w=−∫dVPext​ For a system undergoing a particular process, the work done is, w=−∫dV(V−bRT​−V2a​) This equation is applicable to a

System that satisfies the van der Waals equation of state

Process that is reversible and isothermal

Process that is reversible and adiabatic

Process that is irreversible and at constant pressure

Q. In thermodynamics, the $P - V$ work done is given by $w = - \int d V P_{e x t}$
For a system undergoing a particular process, the work done is,
$w = - \int d V (\frac{RT}{V - b} - \frac{a}{V ^{2}})$
This equation is applicable to a
