Solve the following material and energy balance problem.

In an attempt to provide a process for generating NO in an economical manner, gaseous NH3 with 20% excess oxygen is burned in a reactor. NH3+O2 = NO+H20 The reaction is 70% complete. Unreacted NH3 is separated by equipment and recycled to the reactor feed. a) Draw a diagram of the process. b) Calculate the moles of NO formed per 100 moles of NH3 in fresh feed. c) Calculate the moles of NH3 recirculating per mole of NO formed. Note: Solve by the method of degrees of progress, applying degrees of freedom.
