If 1 mole of an ideal gas expands isothermally at `37^(@)C` from 15 litres to 25 litres, the maximum work obtained is `:`

A

`12.87 J`

B

`6.43 J`

C

`8.57 J`

D

`2.92 J`

Text Solution

Verified by Experts

The correct Answer is:
A
`W_(max,iso)=-2.303 nRT log"(V_(2))/(V_(1))`
`=-2.303xx1xx0.0821xx310xxlog"(25)/(15)`
`=-58.61xx0.22=-1287 J`
(`-ve` sign shows work of expansion i.e., work done by the system)
