The Rate of the Chemical Reaction Involving Two Substances, a and B

Multiple Choice

The rate of the chemical reaction involving two substances, A and B, is measured. It is found that if the initial concentration of A used is doubled, keeping the B concentration the same, the rate doubles. If the concentrations of both A and B are doubled, the rate is eight times that measured in the first experiment. The rate law for this reaction is rate =

A) k[A][B].
B) k[A]²[B].
C) k[A][B]².
D) 2k[A][B].
E) k[A][B]/2.
