Michael is studying the factors that affect reactivity of metals. He wants to test the effect that different concentrations of an acid will have on the reaction of a metal with acid. As he sets up and completes his experiment, which of the following experimental designs would be most likely to help him answer his question? ​

Enzymes affect the reactions in living cells by changing the
