✦ Synopsis

The rate constant for the reaction NHa + OH + NH= + Hz0 was determined by the comparison of the calculated induo tion period data with experiments by the shock tube technique in the range 1360-1840 K, for NHs-Ha-02-_Ar mixtures_ The rate constants can be represented by the expression k = 1012-4g'o-04 exp[(-1.95 f 0.15) kcal/IZT] cm3 mol-' s-t.

The rate constant of the reaction, OH + NH3 -+ Hz0 + NH2, has been measured at temperatures between 230 and 490'K using time-resolved resonance absorption to observe the concemytion of OH radicals..An Arrhenius expression, kI = 2.3 X lO\_" exp(-1.6 kcai mole-'/RT) cm3 molecule-' set , was obtained.
