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.

Respuesta :

The values in the last column marked time will increase progressively.

What is the rate of reaction?

Now we know that the rate of reaction has to do with how fast or slow that a reaction proceeds. Now the concentration of reactants plays a vital role in the determination of the rate of reaction.

If we look at the table, we will see that the mass of the calcium carbonate remains constant but more water was added to the acid. This decreases the concentration of the acid and as such the reaction will take place more slowly as the concentration of acid decreases.

As such, the values in the last column marked time will increase progressively.
