1. The reaction, 2A + B → C, is studied by monitoring the concentration of A. Over the first 3.2 minutes of observation, [A] decreases from 6.68x10-2 mol L-¹ to 6.23x102 mol L. Thus the average rate of this reaction over this time period is A) -4.5×10-3 mol L-¹ s-¹ B) 1.41×10-3 mol L-¹ s-¹ C) 4.69x105 mol L-¹ s-¹ D) 2.34×105 mol L-¹ s-¹ E) 1.17x10-5 mol L-¹ s-1
