A fuel contains 15 mole % ethane and the remainder as methane and is burned completely with pure oxygen at 25 degree C. The products are then cooled to 25 degree C. Assume the reactor is continuous and has a basis of 1 mol/s of fuel gas entering. Assume there is some percent excess oxygen fed into the reactor (the value you choose should not affect your results). Calculate -Q (kW). the rate at which heat must be transferred from the reactor. Now suppose the combustion takes place in a batch reactor with constant volume. Take a basis of calculation of 1 mol of the fuel gas charged into the reactor and calculate - Q (kJ). Again you may assume any percent oxygen for your calculations. An equation that may prove useful is that Delta U_r (T) = Delta H_r (T) - RT times (sigma _gaseous products |v_i| - sigma_gaseous reactants |v_i|) Write a short explanation stating why the results from parts a) and b) don't depend on percent excess oxygen and why they would not change if air was
