WebA reaction with a first order rate will produce a graph of C ( t) that shows exponential decay. However, my derivation provides a linear equation: ln C = − k t + ln C 0. If you determine the natural log of each concentration and plot against t, you will get a line (if the reaction is first order). x = 2, second order WebWe have just seen that first-, second-, and zero-order reactions all have unique, integrated rate-law equations that allow us to plot them as a straight line (y = mx + b) (Table 17.1 “Integrated Rate Law Summary”). When presented with experimental concentration–time data, we can determine the order by simply plotting the data in different ...
