Problem

The equation of state of a gas is p(V−b)=nRTp(V-b)=nRT. If 11 mole of a gas is isothermally expanded from volume VV to 2V2V, the work done during the process is (1) RTln⁡∣2V−bV−b∣RT\ln\left|\frac{2V-b}{V-b}\right| (2) RTln⁡∣V−bV∣RT\ln\left|\frac{V-b}{V}\right| (3) RTln⁡∣V−b2V−b∣RT\ln\left|\frac{V-b}{2V-b}\right| (4) RTln⁡∣VV−b∣RT\ln\left|\frac{V}{V-b}\right|
