A combustion test was performed on a mixture of H₂ and O2 in a steady flow reactor at a pressure of 20 atm. The composition of the exiting products measured in terms of the mole fractions is shown in the table below. Compound H₂O H₂ 0₂ O H OH Mole fraction 0.493 0.498 0 0 0.020 0.005 (a) What is the temperature of the products based on the formation of H₂ and OH from the dissociation of H₂O? (b) What is the temperature of the products based on the formation of H from the dissociation of H₂? (c) Explain the discrepancy between the two methods, if any. Hint: To determine the temperature of the products, it is not necessary to know the initial mole number of H₂ and O2.
