Select the rate law that corresponds to the data shown for the following reaction A B C → Expt. (A) (B) Initial rate 0.012 0.035 0.10 0.024 0.070 0.80 0.024 0.035 0.10 0.012 0.070 0.80
A.Rate = k[B]3✓ Correct
B.Rate = k [B]4
C.Rate = k [A] [B]3
D.Rate = k [A]2 [B]2
Explanation
Let the rate law be r =k [A]x[B]y x y x y x x y x y y 0.024 0.035 0.10 Divide 3 by 1 0.10 0.012 0.035 1 2 ,x 0 0.024 0.070 0.80 Divide 2 by 3 0.10 0.024 0.035 8 2 , y 3 Hence rate equation, 0 3 3 R k A B k B
