Question

30. The iodide ion, I, is oxidized to the hypoiodite ion, IO, by hypochlorite, CIO, in basic solution according to the equation above. Three initial-rate experiments were conducted and the results are shown in the following table. CIO] [1-1 0.017 0 0.052 0.015 Experiment Initial Rate of (mol L) (mol L) Formation of IO 0.015 0.156 0.596 0.476 2 00160.061 Which sets of trials could be used to determine the order of the reaction with respect to each reactant? L1 Trials 1 and 2 Trials 1 and 2 Trials 1 and 3 Trials 1 and 3 ICIO Cio] (A) (B) (C) (D) Trials 1 and 3 Trials 2 and 3 Trials 1 and 2 Trials 2 and 3

Explanation / Answer

for [I-], trial 1 and 3 can be used because in these trials concentration of ClO- is not changing

for [ClO-], trial 1 and 2 can be used because in these trials concentration of I— is nearly constant

So, the correct answer is C

Answer: C
