    Suggestion: The non-linear forms of these kinetic models are more appropriate and better approach than linear forms.

    In every non-linear plot, there is necessary to start with zero ? Excluding zero, the value is changes and did not follows the plot.

      To start with zero is not necessary

    Thank you for explaining.....I have a confusion about the value of alpha and beta for nonlinear model ,will you please tell me how to calculate. And when we plot graph the value of A represent alpha and B (beta) ????

    • @Aminulchem
      @Aminulchem  ปีที่แล้ว +1

      Thank you so much for your comment. For simplicity, I used A and B instead of alpha and beta but you have to write alpha and beta everywhere in the equation. Please check out all other videos and don't forget to subscribe.
