In a solution at a constant H⁺ concentration, iodide ions react with hydrogen peroxide to produce iodine.

The reaction rate can be followed by monitoring the appearance of I₂. The following data are obtained:

(a) Write the rate expression for the reaction.

(b) Calculate k.

(c) What is the rate of the reaction when 25.0 mL of a 0.100 M solution of KI is added to 25.0 mL of a 10.0% by mass solution of H₂O₂(d = 1.00 g/mL)? Assume volumes are additive.
