Chemical Kinetics Reaction Rates
Rate (Ms−1) = k[A][B]1/2[C]2 Overall order: 1 + ½ + 2 = 3 5 = 7/2 or seven−halves order note: when the order of a reaction is 1 (first order) no exponent is written Units for the rate constant: The units of a rate constant will change depending upon the overall order The units of rate are always M/s or Ms–1
