Problem

Acidified hydrogen peroxide and aqueous potassium iodide react to form iodine. It was found that the concentration of iodine was

0.06 \text{ mol dm}^{-3}

after allowing the reactants to react for 30 s. Calculate the average rate of formation of iodine during this time, in units of

\text{mol dm}^{-3} \text{s}^{-1}
