Introduction to Rate Law

AP Chemistry· difficulty 3/5

Initial rates are measured for A + B -> products at constant T.

Trial [A] [B] Rate 1 0.10 0.10 2.0e-3 2 0.20 0.10 8.0e-3 3 0.10 0.20 2.0e-3

Determine the orders with respect to A and B.

  • A

    2nd in A, 2nd in B

  • B

    0 in A, 2nd in B

  • C

    1st in A, 1st in B

  • D

    2nd in A, 0 in B

Explanation

Doubling [A] (trials 1->2) quadruples rate => 2nd order in A. Doubling [B] (trials 1->3) leaves rate unchanged => 0 order in B.
