In a study of the decomposition of ammonia on a platinum surface at 856 °C NH3 →1/2 N2 + 3/2 H, the following data were obtained: 2.00×103 5.00x104 1.50x103 1.00x10-3 2.50x104 1.75x103 NH3), M seconds 998 Hint: It is not necessary to graph these data. (1) The observed half life for this reaction when the starting concentration is 2.00x10 3 M is s and when the starting concentration is 1.00x10 M is (2) The average rate of disappearance of NH3 from t =0s to t = 998 s is |Ms. (3) The average rate of disappearance of NH3 from t= 998 s to t=1.50x103 s is |Ms.
