Question:

Show that the following mechanism is consistent with the rate law established for the iodide–hypochlorite reaction in Exercise 79.

Fast: Slow: Fast: k OCI + HO= k-1 K I + HOCI HOI + OH k3 k-3 HOCI + OH HOI + CI HO + Or


Exercise 79

Hydroxide ion is involved in the mechanism of the following reaction but is not consumed in the overall reaction.

OCI + I OH OIT + CIT

(a) From the data given, determine the order of the reaction with respect to OCl-, I-, and OH-.

(b) What is the overall reaction order?

(c) Write the rate equation, and determine the value of the rate constant, k.

[OCI ], M 0.0040 0.0020 0.0020 0.0020 0.0020 Rate Formation [I], M 0.0020 1.00 0.0040 1.00 0.0020 1.00 0.0020
