The equation of a state of a gas is given by ρ(- b) = nRT. 1 mol of a gas is isothermally expanded from volume V to 2V, the work done during the process is

a
RTln⁡2V−bV−b
b
RTln⁡V−bV
c
RTln⁡V−b2V−b
d
RTln⁡VV−b

detailed solution

Correct option is A

p=nRTV−bW=∫V2V pdV=nRT∫V2V dVV−b ( As, T= constant )=nRTln⁡2V−bV-b=RTln⁡2V−bV−b ( As, n=1)
