A particular reactant decomposes with a half‑life of 109 s when its initial concentration is 0.280 M. The same reactant decomposes with a half‑life of 231 s when its initial concentration is 0.132 M.
A particular reactant decomposes with a half‑life of 109 s when its initial concentration is 0.280 M. The same reactant decomposes with a half‑life of 231 s when its initial concentration is 0.132 M. 1. Determine the reaction order.
(A)1
(B)2
(C)0
2. What is the value and units of the rate constant for this reaction? ????=
Answer:The order of reaction is 2.Rate constant is 0.0328 (M s)⁻¹Explanation:The rate of a reaction is inversely proportional to the time taken for the reaction.As we are decreasing the concentration of the reactant the half life is increasing.a) For zero order reaction: the half life is directly proportional to initial concentration of reactantb) for first order reaction: the half life is independent of the initial concentration.c) higher order reaction: The relation between half life and rate of reaction is:Rate =Half life =where n = order of reactionPutting valuesHence n = 2Putting valuesK = 0.0328...
