Iwo experiments were performed to determine the rate law for the reaction shown below. In both experiments [A] was measured as a function of time in seconds; in experiment 1, 0.200 M B was used and in experiment 2, 0.400 M B was used. In both experiments, the graph of [A] vs time was linear; the slopes of those lines are given in the table. 4. A+B AB Exp Initial [B] (M) Slope of [A] vs time 1 -0.00354 0.200...
