6.11. Zeldovich Equation for NO Synthesis in Quasi-Equilibrium Thermal Systems. Using the Zeldovich equation (6-62), calculate the time required for reaching quasi- equilibrium concentration of nitrogen oxides (NOx) in stoichiometric N2-02 atmospheric- pressure mixture at different thermal plasma temperatures: 3000, 3500, and 4000 K. Analyz- ing activation energies in the Zeldovich equation, find out the limiting reaction responsible for establishing of the quasi-equilibrium concentration of NOx| mol 1 d[NO] dt 1.5. 103. exp cm.s ( 43000 T, K 2) VOZ INOL_(T) [NO]), (6-62)
