For the reaction a+b+c→d+e, the initial reaction rate was measured for various initial concentrations of reactants. the following data were collected: trial [a] (m) [b] (m) [c] (m) initial rate (m/s) 1 0.20 0.20 0.20 6.0×10−5 2 0.20 0.20 0.60 1.8×10−4 3 0.40 0.20 0.20 2.4×10−4 4 0.40 0.40 0.20 2.4×10−4 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]m[b]n 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). part a part complete what is the reaction order with respect to a? express your answer as an integer.
