Two moles of an ideal gas is expanded ir...

Two moles of an ideal gas is expanded irreversibly and isothermally at `37^(@)C` until its volume is doubled and `3.41KJ` heat is absorbed from surrounding. P`DeltaS_("total")` (system +surrounding) is:

A

`-0.52J//K`

B

`0.52J//K`

C

`22.52J//K`

D

`0`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaS_("system")=nR` in `(V_(2))/(V_(1))=2xxRxxln2=11.52J//K`
`DeltaS_("surrounding")=-(3.41xx1000)/(310)=-11J//K`
`Delta_("total")=+11.52-11=+0.52J//K`
