    • 0-H] is the initial ratio of substrate isotopologues, which should be equivalent to the ratio of products at 100% conversion: k cat D K M (FA) = [ P-H ] [ P-D ] [ S 0 -D ] [ S 0 -H ] A similar method is outlined in ref 40. By definition, the competitive KIE reflects the isotope effect on the second-order rate constant.
