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) ]+αn2[(V1 – V2)/(V1 V2)]
(b) nRT log10 [ (V2-nβ)/( V1-nβ) ]+αn2[(V1 – V2)/(V1 V2)]
(c) nRT loge [ (V2-nα)/( V1-nα) ]+βn2[(V1 – V2)/(V1 V2)]
(d) nRT loge [ (V1-nβ)/( V2-nβ) ]+αn2[(V1 V2)/(V1 – V2)]
Answer-a
