The rate of thermal NOx formation was measured for a binary system of N2-O2 in an isothermal tubular reactor. The concentration ratios of nitrogen to oxygen were varied from zero to unity and the reaction temperatures, from 1, 550 to 1, 750 K. As result, the following over-all rate equation of NO formation was obtained.
d [NO] /dτ=7.07×1013exp (-127, 500/RT) [N2] [O2] 1/2
It was seen that, in the temperature range of the present investigation, the values of rate constant of the proposed equation were so small as to be about 1/3 of those of Zeldovich equation.
