18.) In basic aqueous solution, the iodide ion reacts with the hypochlorite ion via the generally agreed mechanism on the right: a.) Identify all intermediates included in this mechanism.
OCl–(aq) + H2O (l) Ý HOCl (aq) + OH– (aq) fast
I– (aq) + HOCl (aq) ↓ HOI (aq) + Cl– (aq) slow
OH–(aq) + HOI (aq) ↓ H2O (l) + OI–(aq) fast
net rxn: I– (aq) + OCl–(aq) ↓ Cl–(aq) + OI–(aq)
b.) Write the rate law that this mechanism predicts for the overall reaction.
