Consider the reaction A+B--->P with the rate law v=k[A]^a[B]^b. In the first experiment, [A]₀=1.6 M and [B]₀=8.00*10^-3 M, and a plot of 1/[B] vs time gives a straight line. In the second experiment, [A]₀= 6.00*10^-3 M and [B]₀= 1.2 M, and a plot of ln[A] vs time gives a straight line. Also, [A]=1.50*10^-3 M when t=0.0893 seconds.

Determine a, b, and k. In experiment 1, determine the time when [B]=4.00*10^-3 M.
