This paper "The problem of discerning Avrami-Erofeev kinetic models from the new controlled rate thermal analysis with constant acceleration of the transformation'' may give you the answer.

It would be a good idea if you could attach your data, eg. in the form of a graph/graphs. Then one could see what shape the kinetic curve has. Is it a curve asymptotically increasing to the upper limit or decreasing curve. Are there inflection points on it? Did you perform the experiment for one initial concentration of adsorbate or for several. Such information may help to choose an equation that will approximate your data correctly. Regards,

Both how to interpret the equation (exponent n) and how to determine the value of the equation parameters can also be found on eg. You Tube. Regards,

I think Avrami kinetic model is a three parameter kinetic model that used to explain the kinetic parameter of adsorption characteristics for more detail please read the attached file.

This paper (Assessment of Various Kinetic Models for

the Pyrolysis of a Microgranular Cellulosemay) give you the answer.

Dear fellow readers

it was very kind and pleasing to get your answers thank you one and all

kindly regards.

The Avrami equation, like many other algebraic equations, can be used to approximate individual kinetic curves. Here, of course, one point of inflection is necessary, and thus slow - fast - slow. However, the physical meaning of the parameters of the equation will always be a problem - especially in relation to the adsorption process. But this is my private opinion. Regards,
