Oxygen is needed for the reactions that cause artifacts to decay in the ocean. Some ancient shipwrecks have been well-preserved deep in the ocean.
Review the information in the data table. Which statement about the
relationship between rates of reaction and concentration of reactants is true?

A. Reactions are slower when there is a lower concentration of
reactants.
B. More information is needed to compare the reaction rates.
C. Reactions are faster when there is a lower concentration of
reactants.
D. Reactions involving certain reactants occur at the same rate no
matter the concentrations of those reactants.
