Calculate the theoretical flame temperature for CO gas burned at constant pressure with 100% excess air, when the reactants enter at 100°C and 1 atm. Solution The solution presentation will be compressed to save space. The system is shown in Figure E10.7. We will use data from Appendix D and the CD in the back of this book. The process is a steady-state flow system. Ignore any equilibrium effects. $$CO(g) + \frac{1}{2}O_2(g) \rightarrow CO_2(g)$$ Basis: 1 g mol of CO(g); ref. temp. 25°C and 1 atm CO 100°C Reactor Air 100°C $$O_2: 0.21$$ $$N_2: 0.79$$ $$T=?$$ $$CO_2: ?$$ $$N_2: ?$$ $$O_2: ?$$
