Solve the following system of reactions occurring in gas phase: + 4NH, +6NO5N, +6H 0 Reaction 1 2N0 N2 +02 Reaction 2 N2 +20, + 2NO, Reaction 3 Let the rates of these reactions be ni moles/time/vol. Assume that the reactor pressure and temperature are constant, and that the gas behaves as ideal gas mixture. The molar feed rate of all the species are specified. We are also given the initial mole fractions of all the species in the reactor. These reactions proceed in constant volume CSTR. Develop the (unsteady) equations required to solve for the evolution of all the molar concentrations in the reactor and effluent volumetric flow rate. You are not asked to solve these equations, but you must show that you have the right number of equations and unknowns to solve. Hint: Try to rearrange the species balance equations to obtain a system of ODES for the evolution of mole fractions of the various components; clearly, you need such equations for only five of the six components as the mole fractions must add to unity. The reaction rates are unspecified functions of total molar concentration of the mixture and the mole fractions
