10 moles of ethane at 25 C and 40% excess air at 100 C are fed to a combustion reactor and a gas at 300 C is obtained. The reactor operates at a pressure of 2 atmospheres. The conversion fraction of ethane is 0.75. The production selectivity of the desired product (CO2) in relation to CO is 5. a) Calculate the molar composition of the outlet gas. b) Calculate the heat of the reactor. use the Perry Manual and the Felder to calculate the specific enthalpies.
