Carbon monoxide burns in air completely to CO2. (a) Write the balanced chemical equation for this reaction. (b) Calculate the stoichiometric fuel to air ratio by mass. (c) For this reaction, at a constant pressure of 1 atm, with the initial and final temperatures of 25 C, calculate the change in enthalpy per unit mass of CO for a stoichiometric fuel–air mixture. (d) What is the quantity in (c) called? (e) If the final temperature of this reaction is 500 C instead, determine the heat lost from the system per unit mass of CO. (f) Calculate the equivalence ratio for a mixture of five moles of CO and seven moles of air. What species would we expect to find in the products other than CO2?
