Based on your knowledge of factors that affect the rates of chemical reactions, predict the trend in the last column of the experimental record. Use
complete sentences to explain the trend you predicted. You do not have to determine exact values for time; just describe the trend you would expect
(increase or decrease) and why it occurs.
