###### FREE Expert Solution

We’re being asked to determine if the mechanism is consistent with the actual rate law: Rate = k[ClO][I].

When a reaction mechanism is given, the rate law can be determined using the slow step in the reaction mechanism.

rate law only involves the reactants
▪ the coefficients of the reactants in the slow step are the order of the reaction with respect to that reactant
▪ Rate Law has a general form of:

k = rate constant
X & Y = reactants
a & b = reactant orders

We're given the reaction mechanism:

###### Problem Details

Consider the following mechanism:

(1) ClO-(aq) + H2O(l) ⇌ HClO(aq) + OH-(aq)         [fast]
(2) I-(aq) + HClO(aq) ⟶ HIO(aq) + Cl-(aq)           [slow]
(3) OH-(aq) + HIO(aq) ⟶ H2O(l) + IO-(aq)           [fast]

(d) Is the mechanism consistent with the actual rate law: Rate = k[ClO-][I-]?
