Ammonia gas enters the reactor of a nitric acid plant mixed with 30% more dry air than is required to form nitric acid and water vapor. If the gases enter the reactor at 348.15 K, if the conversion is 80%, if no side reactions occur, and if the reactor operates adiabatically, answer the following questions: 4NH3(g) +5O2(g) →4NO(g)+6H2O(g) a) Construct a stochiometric table for the following reaction and derive the molar fractions of each species exiting the reactor. [8] b) Write the energy balance for this steady flow process with no shaft work and show schematically in a diagram the path followed by the process. [4] c) Evaluate the MCHP (mean of the heat capacities) to cool the reactants from 348.15K to 298.15K. Use a table format in order to answer this question. [10] d) Estimate the standard heat of reactions ∆H0298 at 298.15K for the reaction. [3] e) What is the temperature of the gases leaving the reactor? Assume ideal gases.
