The concentration of KIO3 can be calculated by multiplying the volume of KIO3 that is being added to the water by its initial concentration that is 0.0024M and then dividing by the total volume that is 50mL in each case.
For the calculation of the rate of reaction, we will just have to divide the change in the concentration of KIO3 by the total time taken for the reaction.
