One kmol of ethane (C₂H6) is burned with an unknown amount of air during a combustion process. An analysis of the combustion products reveals that the combustion is complete, and there are 3 kmol of free O₂ in the products. i) determine the air-fuel ratio and ii) evaluate the percentage of theoretical air used during this process (excess, stoichiometric or deficiency of air).

Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.
