Consider an adiabatic reactor in which the following reaction takes place: CH 4 (g) + 2H 2 O (g) CO 2 (g) + 4H 2 (g) Initially, 25 moles of methane and a stoichiometric amount of water vapor are fed to the reactor at 1369°C. What is the temperature inside the reactor at the end of the reaction if all reactants are consumed? Assume the product gases have the following constant heat capacities: C p (CO 2 ) = 41.3 J/mol °C C p (H 2 ) = 28.9 J/mol °C NOTE: In the reactive systems studied so far, the inlet and outlet conditions were specified and the required heat input could be determined from an energy balance. In another important class of problems, the input conditions, heat input, and product composition are specified, and the outlet temperature is to be calculated. To solve such problems you must evaluate the enthalpies of the products relative to the chosen reference states in terms of the unknown final temperatures, and then substitute the resulting expressions into the energy balance to calculate T
