RATES OF CHEMICAL REACTIONS

REACTION ORDER FOR IODATE ION

OBJECTIVE:

1. To determine the order of a KIO3-NaHSO3 reaction with respect to the iodate ion.
2. To determine a difference on the rate of the reaction when the solution is 10oC higher than a room temperature.

The rate of a chemical reaction is the speed at which reactants are converted to products. Some reactions are very fast and some are very slow. In order for a chemical reaction to occur, particles of the reactants involved must collide with one another at the correct angle and with the correct amount of energy. The factors, which affect the rate of a reaction, are the surface area, nature of the reactants, concentration, temperature, and catalysts.

In this experiment, two solutions will be mixed, and the completion of the reaction will be marked by a color change. One solution contains the iodate...
