A student repeats a reaction several times to test the effects of various changes on the reaction rate. The data table shows the results. Based on
these results, how would decreasing the concentration of the reactants
change the reaction rate?

A. More information is needed to determine what would happen to
the reaction rate.
B. Decreasing the concentration would increase the reaction rate.
C. Decreasing the concentration would decrease the reaction rate.
D. Decreasing the concentration would have no effect on the
reaction rate.
