In thermodynamics, the P - V work done is given by w = - ∫ dVP ext . For a system undergoing a particular process, the work done is, w = - ∫ dV RT V - b - a V 2 . This equation is applicable to a

Options

  1. Asystem that satisfies the van der Waals equation of state.
  2. Bprocess that is reversible and isothermal.
  3. Cprocess that is reversible and adiabatic.
  4. Dprocess that is irreversible and at constant pressure.

Correct answer

A. system that satisfies the van der Waals equation of state.

Step-by-step solution

(W=- P_ ext d v ) From van der waal equation of state for one mole gas (p+ a v² (v-b)= RT ) (p= RT (v-b) - a v² ) For reversible process (p_ ext =p_ gas ) (W=- RT (v-b) - a v² ) process is only not applicable for irreversible process.
