Step 1

The zero-order, first-order, and second-order reaction follows the equation (1), (2), and (3) respectively. [A] is the concentration of a reactant at a time, t and [A]o is the concentration of the reactant at the time t = 0.

Step 2

The graphs, [A] vs t, ln[A] vs t, and 1/[A] vs t were plotted. It was found that the graph 1/[A] vs t is a straight line. Hence, the given reaction is a second-order reaction. The table and graph for 1/[A] vs t are as follows: help_outlineImage Transcriptionclose[Cl20 t(sec) t(sec) 1/ICl20s] 0.09 11.11111 0.0451 1 22.17295 0.0301 2 33.22259 0.0226 3 44.24779 4 0.0181 55,24862 1/[C205] vs t 60 50 40 30 20 10 4.5 0.5 1.5 2 2.5 3.5 4 time (sec) en O 1/ICl20s fullscreen
Step 3

The order of the reaction w.r.t. concentration of Cl2O5 is two. ...
