An Experimental Drug, D, Is Known to Decompose in the Blood

An experimental drug, D, is known to decompose in the blood stream. Tripling the concentration of the drug increases the decomposition rate by a factor of nine. Write the rate law for decomposition ofD.

A) The rate law is rate = k[D]³
B) The rate law is rate = k[D]²
C) The rate law is rate = k[D]
D) The rate law is rate = k[D]⁹
E) None of the above
