Ethane gas is burned in a steady-flow process with 30% excess air, both of which enter separately at 25 0 C and 1 atm. Assume the reaction goes to completion, and the products leave as a mixture at 1 atm and the environmental temperature of 25 0C. The water in product is assumed to be all liquid.
Determine the entropy change for the reaction its self, in kJ/K and The total entropy change for the overall process, in kJ/K per kg mole of fuel.
