The
reaction rate of a
chemical reaction, that is, the speed of production of products or
reactants, may generally be expressed as rate =
k [a]^
x where [a] is the
molar concentration of reactant (there may be several),
x is the order for that reactant, and
k is a constant. Order establishes the mathematical relation of concentration to rate; eg. for an order of 2, if the concentration doubles, the rate quadruples.
Rate is often expressed in mols per liter-second.
