The initial rate of the reaction of species A and B A+ 2 B C was measured at a temperature of 25 C for various initial concentrations of A and B. Data are collected in the table. Determine the rate equation from these data. What is the overall order of the reaction? What is the value of the rate constant? (Give the appropriate units of k.) Initial Concentrations, mol/L Initial Rate, mol L-1 s-1 1.80 x 10-4 7.20 x 10-4 3.60 x 10-4 Experiment 1 0.250 0.250 2 0.500 0.250 3 0.250 0.500
