Chemistry - Thermodynamics - I Question with Solution | TestHub

$W=-\int P_{\text{ext }}dv$ From van der waal equation of state for one mole gas $p+\frac{a}{v^2}(v-b)=\mathrm{RT}$ $p=\frac{\mathrm{RT}}{(v-b)}-\frac{a}{v^2}$ For reversible process $p_{\text{ext }}=p_{\text{gas }}$ $W=-\int \frac{\text{RT }}{(v-b)}-\frac{a}{v^2}$ process is only not applicable for irreversible process.
