Reaction Order from the Integrated Rate Law

Determining the Reaction Order from the Integrated Rate Law 

Suppose you don t know the rate law for a reaction and don t have the initial rate data needed to determine the reaction orders (which we did have in Sample Problem 16.3). Another method for finding reaction orders is a graphical technique that uses concentration and time data directly. 

An integrated rate law can be rearranged into the form of an equation for a straight line, y = inx - b, where m is the slope and b is the y-axis intercept. For a first-order reaction, we have 

Therefore, some trial-and-error graphical plotting is required to find the reaction order from the concentration and time data
