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

`-2.01 xx 10^3 J`

B

`+2.81 xx 10^3 J`

C

`2.01 xx 10^(-3) J`

D

`+2.01 xx 10^(-6) J`

Text Solution

Verified by Experts

The correct Answer is:
A
`W =- 2.303 nRT " log " (V_2)/(V_1)`
`W =- 2.303 xx 16/32 xx 300 xx 8.314 " log " 25/5 `
`W =- 2.01 xx 10^3 j `
