Calculate the maximum work done in expanding `16g` of oxygen at `300K` occupying volume of `5dm^(3)` and isothermally untill the volume become `25dm^(3)`?

A

`-2.01xx10^(3)J`

B

`2.01xx10^(-2)J`

C

`+2.81xx10^(3)J`

D

`+2.01xx10^(-6)J`

Text Solution

Verified by Experts

The correct Answer is:
A
`W=-2.303nRTlog.(V_(2))/(V_(1))`
`W=-2.303xx((16)/(32))xx8.314xx300log.(25)/(5)`
`W=(-2.303xx8.314xx300)/(2)log5`
`W=-2007.49J`
