## pseudo rate constant

https://doi.org/10.1351/goldbook.P04933
A term sometimes used for a @R05137@. For example, if the rate equation is: $v=k\ \text{[A]}\ \text{[B]}$ the function $$k\ \text{[A]}$$ is the pseudo first-order @O04322@ (or first-order @R05137@) with respect to B. Similarly, $$k\ \text{[B]}$$ is the pseudo first-order @O04322@ (or first-order @R05137@) with respect to A. The term pseudo @O04322@ is particularly useful when the concentration of one reactant is much greater than that of another.
