In a study of the decomposition of ammonia on a tungsten surface at 1100 °C NH31/2 N,+3/2 H2 the concentration of NH, was followed as a function of time. It was found that a graph of [NH3] versus time in seconds gave a straight line with a slope of -4.52x10-6 M s and a y-intercept of 5.82×10³ M. Based on this plot, the reaction is order in NHz and the rate constant for the reaction is Ms.
