In an experiment, calcium carbonate reacted with different volumes of hydrochloric acid in water. one of the products formed during the experiment was carbon dioxide. the time taken for 0.89 ml of carbon dioxide to form was recorded. a partial record of the experiment is shown.
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.
