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?
Conditions
Original
Higher concentration
Higher temperature
Metal added
Reaction Time (5)
10 seconds
5 seconds
5 seconds
5 seconds
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.

Decreasing the concentration would decrease the reaction rate (option c)

The aforementioned statement is due to the fact that when a substance's concentration is high, it will quickly perform the chemical reaction as there are more particles reacting with one another. Conversely, if there is less of a concentration, then the reaction rate would decrease as there are little particles reacting with one another.
