 The basis for a graphical rate law rests on the rate ("v") vs. substrate concentration ([S]) plots discussed above.For example, in the simple cycle discussed with regard to different-excess experiments a plot of vs. [B] and its twin vs. [A] can provide intuitive insight about the order of each of the reagents.If plots of vs. [B] overlay for multiple experiments with different-excess, the data are consistent with a first-order dependence on [A].
