Question

What is the order of the following reaction? Determine rate constant. (without using a graph)

For a reaction that has a rate constant, k=1x10-2 and [A]o = 0.1M, would it have a longer half life it was first or second order? (MUST show work!)

Answer 1

3 Given (t -8 3) e lot atsume it as Xero ordor rxn, Both doesnt match row,fiding K fro-5) which means not a zero orde>r ryn 9 38-83 K 93 findiną from (t- 33) 2.303 a Qo 30 2303 loq 8 5 IC 83 2.303 bq& Both K Value are difterent first order re action also
