Question

6 moles of an ideal gas expand isothermally and reversibly from a volume of 1 litre to a volume of 10 litres at `27^(@)C`. What is the maximum work done
A. 47 kJ
B. 100 kJ
C. 0
D. 34.465 kJ

Answer 1

Correct Answer - D
Workdone in isothermal reversible expansion `W=PDeltaV`
`W=-2.303 nRTlog.(V_(2))/(V_(1))`
`=-2.303xx6xx8.314xx300log.(10)/(1)`
=34464.8 Joule = 34.465 kJ.
