The combustion of propane in the presence of O2 can produce either CO2 (desired) or CO (undesired) according to the following reaction schemes: Our initial feed consists of propane and 60% excess O2 for the desired reaction. The yieldof CO2 is 55%, and the selectivity of CO2 relative to CO is 11. Based on this information,calculate the composition of the output using molecular species balances.
