Question:

A 6-m3 rigid tank initially contains a mixture of 1 kmol of hydrogen (H2) gas and the stoichiometric amount of air at 25oC. The contents of the tank are ignited, and all the hydrogen in the fuel burns to H2O. If the combustion products are cooled to 25oC, determine
(a) The fraction of the H2O that condenses
(b) The heat transfer from the combustion chamber during this process.
