The catalyzed decomposition of NH3 (g) at high temperature is represented by the equation above. The rate of disappearance of NH3 (g) was measured over time for two different initial concentrations of NH3 (g) at a constant temperature. The data are plotted in the graph below. Time (s) On the basis of the data in the graph, which of the following best represents the rate law for the catalyzed decomposition of NH3 (g)? A Rate = k B Rate = k[NH3] %3D c) Rate = k NH3 D Rate = k[N2][H2] 2 NH. (9) n, N. () - 3H, (0) catalyst +N2 g ['HN]
