The reaction rate
of a chemical reaction
, that is, the speed of production of products or reactants[?]
, may generally be expressed as rate = k
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.
