Ethane burns to completion with 100% theoretical air in a steady process. The reactants enter at 298 K and the products exit at 298 K. Determine the heat of reaction (per kmole of fuel) for this process (a) assuming the water in the products is all vapor, and (b) assuming the water in the products is all liquid. Compare these results to published values for the lower heating value and the higher heating value for ethane.
