Question

In a study of the decomposition of ammonia on a platinum surface at 856 °C NH 12N2+3/2 H2 the following data were obtained: IN). M1341 102 6.70x10 510.68-10 1.34x10-2 3.35x103 1.50x10 1.68x10-3 1.75x103 seconds 1000 Hint: It is not necessary to graph these data. The observed half life for this reaction when the starting concentration is 1.34x102 M is starting concentration is 6.70x103 M is s and when the S. The average rate of disappearance of NH, fromt-0s to t-1000 s is The average rate of disappearance of NH, from-1000 s to t-1.50x10 s is Based on these data, the rate constant for thisorder reaction is Ms Ms Ms

Explanation / Answer

1) 1000 , 500

2) 6.7x10-6

3)  6.7x10-6

4) 0 , 6.7x10-6

As the half life of the reaction decreases with decrease in concentration of the reactants the reaction is a zero order reaction.
