Experiment 7 Rates of Chemical Reactions: The Todination of Acetone Objective Dermination the rule of chemical reaction Die The me of chemical reaction depends on went to the nature of the reaction, the centrations of the reactions, the temperature, and the prince of a posible catalyst Is the experiment we will determine the rate le for reaction by changing some of the above variable in this experiment we will study the kinetics of the action between die andere The indination of sotone is candy investigated because iodine (to har i denpyetle town color As the one in edinted and the dise converted to the diseation, the color will disappear ather of the reaction to emily mentored Westerse of this matce by simply making the limiting rectantialce of edition.

10.00 ml flask (Note: use these concentration values in this lab regardless of what the stockroom lists as the actual concentration.) 2. Start the stopwatch as you add the iodine to the 125 ml flask. Swirl the flask (which helps to prevent acetone evaporation) until the yellow color disappears, then halt the stopwatch. It may help to place the flask on a white piece of paper to help discern when the color disappears. Record the time elapsed in seconds. 3. Repeat this reaction mixture until 3 trials of the same experiment are within 20 seconds of each other. 4. Determine the average time elapsed in seconds for this experiment. Repeat this process for each of the four experiments listed in the table below. 96
