The kinetics of a reaction A + B + C → D are being studied. By comparison with the first experiment it is found that i) Keeping [B]0 and [C]0 constant and increasing [A]0 by a factor of 4 causes the reaction to go eight times faster initially. ii) Keeping [A]0 and [C]0 constant and decreasing [B]0 by a factor...
