2. The reaction A + 2B - C has a second order rate law, and the reactants have the same partial orders. An experiment was carried out with this reaction, using an 800 mM solution of A and 1500 mM solution of B. An analysis conducted 15.0 seconds later showed that only 15.5 % of A remained. a) Determine the rate constant. b) Compare the half-life of both reactants. c) What is the concentration of product C after 10 seconds?
