pseudo rate constant

A term sometimes used for a rate coefficient. For example, if the rate equation is:
v = k [A] [B]
the function k [A] is the pseudo first-order rate constant (or first-order rate coefficient) with respect to B. Similarly, k [B] is the pseudo first-order rate constant (or first-order rate coefficient) with respect to A. The term pseudo rate constant is particularly useful when the concentration of one reactant is much greater than that of another.
