5mol of an ideal gas at 27^(@)C expands ...

`5mol` of an ideal gas at `27^(@)C` expands isothermally and reversibly from a volume of `6L` to `60L`. The work done in `kJ` is

A

`-14.7`

B

`-28.72`

C

`+28.72`

D

`-56.72`

Text Solution

Verified by Experts

The correct Answer is:
B
`w = -2.303 nRT "log"(V_(2))/(V_(1))`
`=- 2.303 xx5 xx 8.314 xx 300 "log"(60)/(6)`
`=- 28.72 kJ`
