Entropy Change for System and surrounding

System And Its Surroundings And Types Of System

The total entropy change (DeltaS_("total")) for the system and surrounding of a spontaneous process is given by

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]
