Kinetics How fast does a reaction proceed? Kinetics terms: Reaction rate Order of reactant Rate Law
Background image of page 2
Reaction Rate A B rate = - [A] t rate = [B] t [A] = change in concentration of A over time period t [B] = change in concentration of B over time period t 13.1 Reaction rate is the change in concentration of a reactant or a product with time ( M /s).

The Rate Law The Rate Law expresses the relationship of the rate of a reaction to the concentrations of the reactants raised to some powers. a A + b B c C + d D Rate = k [A] x [B] y k represents the rate constant ; determined experimentally. Units depend on x & y.

Order of Reaction x y represent the order of reactant A & B, respectively. These numbers can be integers, fractions, or even negative numbers. The order of each reactant must be determined experimentally.
