Response Details:
a) 0      rate = k[A]0      If the concentration doubles, the rate does not change.
b) 1      rate = k[A]1     If the concentration doubles, the rate doubles (multiplies by two).
c) 2      rate = k[A]2     If the concentration doubles, the rate quadruples (multiplies by four).
d) 3      rate = k[A]3     If the concentration doubles, the rate multiplies by eight.
e) 1/2   rate = k[A]1/2   If the concentration doubles, the rate mutiplies by .
