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

question 37

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.
