Although the wide applications of the fractional order of dierential equations hasbeen reported in the physics, astronomy, and bioengineering elds, little attention has beenpaid to the fractional kinetic models in the literature. In this research, we are conned with theapplication of Jacobi polynomials for solving fractional order of l dierential equation arising inchemical reaction model into the Palm oil in the sense of fuzzy context. The results demonstratethe capability of the method which can be a reliable numerical technique to be utilized in thesimilar reaction models.
