16g of oxygen gas expands isothermally ...

16g of oxygen gas expands isothermally and reversibly at 300 K from 10 `dm^(3)` to 100 ` dm^(3)` . The work done is ( in J)

A

`-2963 J`

B

`-2368 cal`

C

`-2872 J`

D

`-2895 J`

Text Solution

Verified by Experts

The correct Answer is:
C
`n=(16)/(32) =0.5`
`W_("max") =-2.303 nRT log_(10)""((V_(2))/(V_(1)))`
`=-2.303xx0.5xx8.314xx300xx log""(100)/(10)`
`=-2872 J`
