In a study of the decomposition of ammonia on a platinum surface at 856^degree C NH_3 rightarrow 1/2 N_2 + 3/2 H_2 the following data were obtained: The observed half-life for this reaction when the starting concentration is 1.02 times 10^-2 M is []s and when the starting concentration is 5.10 times 10^-3 M is []s. The average rate of disappearance of NH_3 from t = 0 s to t 997 s is [] M s^-1. The average rate of disappearance of NH_3 from t = 997 s to t = 1.50 times 10^3 s is [] M s^-1 Based on these data, the rate constant for this [] order reaction is [] M s^-1.
