During the reaction A+B to C, reagant B was held in excess at a concentration of 0.150 M. The order of B was 1. Next, by plotting collected data as ln [A] vs. time, a straight line was made with slope= -0.3045, which means reagant A follows first order kinetics. The integrated rate law of this is of the form ln [A]= -k[B]^n*t + ln[A]_0. Using this rate law, and the collected data, calculate the rate constant for the reaction. Also specify units.
