Question
a) Describe the chemistry that was occuring in the experiment between the time when solutions A & B were mixed and STOP TIME
b) For Kinetic Trial 2, Alicia was distracted when the color change occurred but decided to record the time lapse read from her watch. Will this distraction cause an increase or decrease in he slop of the log (rate) vs log [I-]0? Explain.
c) - When doing the kinetic trial , Susan forgot to include the deionized water. Will this omission hasten or delay the formation of the blue color in the trials (Exclusive of Trial 6)? Explain.
-When doing the kinetic trial, Oscar mistakenly omitted the sodium thiosulfae solution. How will this omission change the appearance of the resultant solution (from mixing solutions A&B) from that of a correctly completed expiernment? Explain your reasoning.
- When doing the kinetic trial, Peyton mistakenly omitted the starch solution from the kinetic trials. How will this omission change the appearance of the resultant solution (from mixing solutions A&B) from that of a correctly completed expiernment? Explain your reasoning.
- Of the three chemists above, Which chemist will have the most accurate results? Explain.
d) State the effect that each of he following changes has on the reaction rate in this experiment (increase, decrease, or no effect). (Assume no volume change for any of the concentration changes.)
- An increase in the H2O2 concentration. Explain.
- An increase in the volume of water in solution A. Explain.
- An increase in the Na2S2O3 concentration. Explain.
-The subsititution of a 0.5% starch solution for one at 0.2%. Explain.
e) The temperature of the warm water bath is recorded too high. How will this technique error affect the reported activation energy for the reaction ---- too high or too low? Explain.
