A comparative study for fractional chemical kinetics and carbon dioxide CO₂ absorbed into phenyl glycidyl ether problems

The essential objective of this work is to implement Adam Bashforth’s Moulton (ABM) and Haar wavelet method (HWM) to solve fractional chemical kinetics and another problem that relates the condensations of carbon dioxide (CO₂) and phenyl glycidyl ether (PGE) with two variety of Drichlet and a mixed set of Neumann boundary and Drichlet type conditions respectively. We have been solved the above system of differential equations by Adam Bashforth’s Moulton and Haar wavelet operational method where this technique is to convert the system of differential equations into the system of algebraic equation which can be solved easily. This work is expects to contribute the vast advantage of Haar wavelets in chemical science. The Adam Bashforth’s Moulton and Haar wavelet method is impressive and convenient for obtaining numerical solutions of chemical engineering type problems. A complete agreement is acheived between Adam Bashforth’s Moulton solution and Haar wavelet solution. To manifest about the performance and applicability of the method, two test examples are deliberated.
