Question 10 For the reaction A+B+CD+E, the initial reaction rate was measured for various initial concentrations of reactants. The following data were collected: Trial 1 2 3 4 Initial rate [A] [B] [C] (M) (M) (M) (M/s) 0.40 0.40 0.40 1.2x10-4 3.6x10-4 0.40 0.40 1.20 0.80 0.40 0.40 4.8x10-4 0.80 0.80 0.40 4.8x10-4 V Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction between A and B, aA + bB cC + dD The dependence of the reaction rate on the concentration of each reactant is given by the equation called the rate law: rate = k[A] [B]" where k is a proportionality constant called the rate constant. The exponent m determines the reaction order with respect to A, and n determines the reaction order with respect to B. The overall reaction order equals the sum of the exponents ( m+n).
