Reaction Kinetics: Rate Laws

The rate of a reaction is the change in concentration with respect to time of a product. The rate equals the rate constant times the concentrations of the reactants raised to their orders. A rate constant is a proportionality constant in the rate law that is a measure of the intrinsic reactivity of the reaction. The rate constant does not depend on the concentrations of reactants but the rate does (if it is not zero order).

There is not enough information to solve this problem. The order of a reaction must be experimentally determined. The order and stoichiometry of a reaction are causally disconnected.

rate = k [A]³
rate = k [A]² [B]
rate = k [A] [B]²
rate = k [A] [B] [C], etc.
