The kinetics of the reaction between two substances, A and B,was investigated using the method of initial rates in a series ofthree experiments.
In the first experiment, the initial concentration of A was0.400 mol L-1, the initialconcentration of B was 0.300 mol L-1,and the rate of the reaction was observed to be1.72 mol L-1 of product perminute.
In the second experiment, the concentration of A was kept the same(0.400 mol L-1), and the concentrationof B was doubled to 0.600 mol L-1. Inthis experiment, the rate was observed to be 3.44mol L-1 of product per minute.
In the third and last experiment, the concentration of B was keptthe same as in the second experiment (0.600 molL-1), and the concentration of A was tripled to1.20 mol L-1. In this experiment, therate was observed to be 31.0 mol L-1 ofproduct per minute.
