A Graphical Method for the Estimation of k and

Taking logarithm on both sides of Equation 2.39, we get an equation for n as 

Note that this method of parameter estimation does not hold good for first-order reaction (n = 1). The values of k and n estimated using the procedure presented in this section are to be taken only as approximate initial guess values. The integral method will give more accurate estimates of k and n.
