1. In an attempt to provide a means of generating NO cheaply, gaseous NH3 is burned with 30% excess O2. The reaction is 4NH3+5O2 4NO+6H2O. The reaction is 64% complete. The NO is separated from the unreacted NH3, and the latter recycled as shown in the figure. Determine the following: i) the moles of NO formed per 100 moles of NH3 fed, ii) the moles of NH3 recycled per mole of NO formed, iii) the single-pass conversion and the overall conversion of NH3 and iv) the gas composition leaving the separator
