Constant time interval method for analysis of reaction rate data

In the study of chemical kinetics, many integrated reaction rate equations have the form In [ f (A) + a ] = bt + c , where a , b , and c are constants and f (A) is some function of the concentration of a reactant (or product) which can be calculated from the data. The left‐hand side of this equation cannot be graphed versus time if the constant a is unknown. However, it is shown that f (A2) varies linearly with f (A 1 ) if A 2 is the concentration of reactant measured at a constant time interval later than A 1 . The constants a and b can be determined from the linear graph. A number of specific examples are considered.
