The table below shows the concentration of a reactant (A) measured at various times since the initiation of the reaction. 0 5 11 19 31 46 63 78 T 95 0.970 0.794 0.625 0.454 0.281 0.154 0.078 0.043 0.022 t/min [A]/mol L-1 (a) Draw a graph of concentration of the reactant versus time. Estimate the concentration of the reactant and the rate of reaction (as given by -d[A]/dt) at the following times: 20 min, 40 min, 60 min. (b) From your graph in (a) estimate the initial rate of reaction. c) Using the rates and concentrations from (a) and (b) plot a graph of rate versus concentration. What can you deduce about the dependence of the rate on the concentration of the reactant? d) From the graph in (c) estimate the rate constant for this reaction.
