B. Influence ofTemperature onReaction RatesMost chemical reactions speed up when the temperature is increased.Chemists sometimes use the rough rule of thumb that a 10 C increase intemperature will double the rate of a reaction. The influence of temperatureon a reaction rate will be studied using the same reactions that were usedin Part A. Reaction temperatures wil be established and maintained bywater baths.Procedure1. 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 AMeasure the NaHSOs solution into a clean, dry 15-cm test tube as youdid in Part A2. 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 beakercontaining about 150-mL of water. The water is adjusted to the appropriate temperature. Leave them in the bath for at least 5 minutesbefore mixing

Question

8. What are water baths used for in Part B?

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.
