3 Carbon monoxide is burned (completely) with excess air at 1atm in an adiabatic reactor. The reactants are fed at 25^(@)C and the final temperature (i.e., the adiabatic flame temperature) is 1400^(@)C. Calculate the percentage excess air fed to the reactor. If the percentage excess air were increased, how would the adiabatic flame temperature change and why would it change in this manner? [Given: CO+1//2O_(2)rarrCO_(2),DeltaH^(@)c=-. 282.99kJ//mol; Specific enthalpy in kJ//mol of the CO,CO_(2),O_(2),N_(2) at 1400^(@)C are 44.95,71.89,47.07,44.51 respectively]
