WebThe concentration v/s time graph for a first-order reaction is provided below. For first-order reactions, the equation ln [A] = -kt + ln [A] 0 is similar to that of a straight line (y = mx + c) with slope -k. This line can be … WebWhat about reactions that are first-order in two reactants, X and Y, and therefore second-order overall? Rate = k(X)(Y) A plot of 1/(X) versus time won't give a straight line because the reaction is not second-order in X. Unfortunately, neither will a plot of ln (X) versus time, because the reaction is not strictly first-order in X.
