In a reversible process, Delta S_(sys) + Delta S_(surr) is

In a reversible process, the value of Delta S _(sys) + Delta S_(surr) is

Assertion : In a reversible process, DeltaS_("universe") is zero. Reason : Entropy is an extensive property.

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" ) .

One mole of solid iron was vaporized in an oven at 3500 K . If iron boils at 3133 K abd enthalpy of vaporization is 349 KJ mol^(-1) , determine DeltaS_("system"), DeltaS_("surrounding") and DeltaS_("universe") . (Oven is considered as surroundings).

Pressure of 10 moles of an ideal gas is changed from 2 atm to 1 at against constant external pressure without change in temperature. If surrounding temperature (300K) and pressure (1 atm) always remains constant then calculate total entropy change (DeltaS_("system")+DeltaS_("surrounding")) for given process. [Given : ? n2 = 0.70 and R = 8.0 J/mol/K]
