6. Consider the following chain-reaction mechanism for the high temperature formation of nitric oxide (NO): O + N KAS k2f N+0 d[NO] d[N] a. Write out expressions for dt dt b. Assuming N atom exist in steady-state and that the concentrations of O, O and N are at their equilibrium values, simplify your expression obtained above for d[NO] dt and T = 2100 K p = 0.167 kg/m MW = 28.778 kg/kmol NO+N NO+O c. Write out an expression for the steady-state N-atom concentration used in part b. For the conditions given below, and using the assumptions of part b., how long does it take to form 50 ppm (mole fraction* 106) of NO? d. Xo.eq = 0.000076 (mole fraction) Xo2.eq = 0.003025 (mole fraction) XN2.eq = 0.726 (mole fraction) Kf = 1.82* 1014 exp[-38,370/T] cm/gmol-s 6.
