For a reversible reaction ΔSsystem+ΔSsurrounding is-
ΔSsurroundings=+959.1JK−1mol−1 and ΔSsystem=163.1Jk−1mol−1 Then the process is
Two moles of ideal monoatomic gas was taken through isochoric heating from 100 K to 800 K. If the process is carried out irreversibly (one step) then ΔSsystem + ΔSsurrounding is
[Given : ln 2 = 0.7 and R = 2 cal/mol K]
