7. In order to determine the rate law for this reaction, experiments were run under ''pseudo-order'' conditions, similar to what you used in your kinetics laboratory experiment. To do this, concentration vs. time data were recorded for several different starting concentrations of A and B. In all cases the [A]>> [B] so that the [A] did not change significantly during the course of the experiment. For the first data set, a plot of ln[B] vs. t gave a curved line, but a plot of 1/[B] vs. t gave a straight line. What does this information tell about the kinetics of this reaction. Choose the one best answer. (a) The reaction is second order in B. (b) The reaction is first order in B. (c) The reaction is first order in A. (d) The reaction is second order in A. (e) The reaction is second order overall (ab) The reaction is fourth order overall.
