The decomposition of ammonia on a platinum surface at 1129 K occurs according to the

Question

following reaction: 2NH3 (g) �¨ N2(g) + 3H2(g). Use the following kinetic data which report the
variation of ammonia concentration in the gas phase with time to evaluate the order of reaction, rate
constant for the reaction at 1129 K and the half life. Justify why the reaction follows the order you
have determined.
[NH3] (x10-3 M) 2.10 1.85 1.47 1.23 0.86 0.57 0.34
Time (s) 0 200 400 600 800 1000 1200

Answer 1

please explain 'Use the following kinetic data which report the
variation of ammonia concentration in the gas phase with time to evaluate the order of reaction?' am confused I did plot found it was a 0zero order but then what.i need to know the key points of this question and what I should do when I see a question like this.thank you dr bob
