Question

Calculate the absolute entropy of the following: a) 2.5 moles of Ar gas at p = 0.25 bar; b) 0.75 mole of O3 gas at p = 2.75 bar; c) 0.45 mole of a mixture of N2 (X=0.78) and O2 (X=0.22) at P(total) = 1.00 bar

Robert · Accepted Answer

moles of Ar , n = 2.5 mol
pressure, p = .25 bar
Answers:-
(a). 
Then , the absolute entropy S is given as
    S = nRln(p/po)
       = 2.5*8.314*ln(.25)
      = 2.5*8.314*(-1.39)
     = - 28.89 JK-1mol-1
(b) . Moles of O
3
 , n =0.75 mol
      pressure, p = 2.75 bar
Then , the absolute entropy S is given as
    S = nRln(p/po)
       = 0.75*8.314*ln(2.75)
       =0.75*8.314*1.
