โฆ Synopsis
The gas-phase reaction between Na metal vapor and NzO has been examined at near morn tempct;rturr in a fast-flow low ptesure reactor using pho.ometric methods. The reaction rate wab detcrminrd tn h k, = 7.6 x 10" rm3/mole set at 330ยฐC and gives an activation energy ofabout I IO0 cal/m& ohepn compared with published high-temperature rate data. The reactmn is ac,:ompanied by Na D-line rhem,. lutnh~escecence, the intensity of which is found to correspond to Naatom removal;? kinetic mcchsrurm Is suggested to explain this behavior.
