1.	Two mole of an ideal gas is expanded irreversibly and isothermally at 37^(@)C until its volume is doubled and 3.41 kJ heat is absorbed from surroundings. Delta S_("total") (system + surroundings) is
Answer» `-0.52` J/K 0.52 J/K 22.52 J/K 0 Solution :`Delta S_("total") = Delta S + Delta S_("SURR")` `=(N C_(V) = "LN" (T_(2))/(T_(1)) + nR "ln"(V_(2))/(V_(1))) + ((-Q)/(T))` `=(2 xx 8.314 xx ln 2) + ((-3.41)/(310)) = 0.52J//K`
