effective molarity (effective concentration)

The ratio of the first-order @O04322@ of an @I03130@ reaction involving two functional groups within the same @M03986@ to the second-order @O04322@ of an analogous @I03098@ @E02035@. This ratio has the dimension of concentration. The term can also apply to an @E02177@.
