4. You are feeding 1 mole of C8H18 as a vapor and stoichiometric amount of air (21% oxygen, 79% nitrogen) at Pin = 1 bar and Tin = 25 °C in a reactor. They react to completion and the exit gas stream is at Pout = 1 bar and Tout = 150 °C. Calculate the maximum work that can be produced, assuming no heat transfer and IGM (useful information: Cp,C8H18 = -23.87 J/mol K, Cp,O2 = 28.31 J/mol K, Cp,N2 = 31.44 J/mol K, Cp,H2O = 34.51 J/mol K, Cp,CO2 = 17.46 J/mol K).
$C_8H_{18} + \frac{25}{2}O_2 \rightleftharpoons 9H_2O + 8CO_2$
