Two mole of ideal gas is expanded irrversibly & isothermally at `27^(@)` C until its volume is double and `3.3 kJ` heat is absorbed from surrounding . Determine `DeltaS_("System")` & `DeltaS_("surrounding" )`.

Text Solution

Verified by Experts

`DeltaS_("system") = nR ln .(V_(1))/(V_(2)) rArr 2 xx R xx ln rArr 11.52 J//K`
`DeltaS_("surrounding") = - (3.3 xx 1000)/(300) rArr -11 J//K`
