The progress of a reaction is tracked by following the concentration of one reactant as it is consumed. The table gives the concentration of that reactant at several times. a Use graphing software to plot the dats as [R] versus time, and dotermine the average rate for the first 15 s and the average rate from t=100 to t=125 s. Enter the rates as positive valuea. Rote (tromt=0 to t=15s)= Rote ( from t=100 to t=125s)= M/s
