<P> where ( A ) and ( B ) express the concentration of the species A and B ( usually in moles per liter ( molarity , M ) ) . The exponents x and y are the partial orders of reaction for A and B and the overall reaction order is the sum of the exponents . These are often positive integers , but they may also be zero , fractional , or negative . The constant k is the reaction rate constant or rate coefficient of the reaction and has units of 1 / time . Its value may depend on conditions such as temperature , ionic strength , surface area of an adsorbent , or light irradiation . </P>
