10. Work done by a system under isothermal change from a
volume V1 to V2 for a gas which obeys Vander Waal’s equation (V – βn)[ P + (αn2/v)= nRT
(a) nRT loge( V2 – nβ/V1– nβ) + α n2(V1 -V2)/V1V2
(b) nRT log10 ( V2 – αβ/V1– αβ) + α n2(V1 -V2)/V1V2
(c) nRT loge ( V2 – nα/V1– nα) + β n2(V1 -V2)/V1V2
(d) nRT loge ( V1 – nβ/V2 – nβ) + α n2 (V1V2/ (V1 -V2)
