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

zero

B

`-2875J`

C

`+2875J`

D

inifinite

Text Solution

Verified by Experts

The correct Answer is:
B
`W=-2.303 nRT log""(V_(2))/(V_(1))`
`= - 2.303 xx (16)/(32) xx8.314xx300log "" (100)/(10) `=-2872 J`
