B. Influence of Temperature on Reaction Rates Most chemical reactions speed up when the temperature is increased. Chemists sometimes use the rough rule of thumb that a 10 C increase in temperature will double the rate of a reaction. The influence of temperature on a reaction rate will be studied using the same reactions that were used in Part A. Reaction temperatures wil be established and maintained by water baths. Procedure 1. For each trial listed in Table 11.3, measure the KIO, solution and dis- tilled water into a clean, dry 10-cm test tube as you did in Part A Measure the NaHSOs solution into a clean, dry 15-cm test tube as you did in Part A 2. Before mixing the reactants, bring them both close to the same tem- perature by placing them in a water bath made from a 250-mL beaker containing about 150-mL of water. The water is adjusted to the ap propriate temperature. Leave them in the bath for at least 5 minutes before mixing
