Enzymatic reactions are used extensively to characterize biologically mediated reactions in environmental engineering. Proposed rate expressions for en enzymatic reaction are given below where [S] is the substrate concentration and v0 is the initial rate of reaction. Which formula best fits the experimentaldata?
