Technical report: the performance test of implicit backward differentiation formula on Robertson’s chemical reaction model / Najihah Md Nasib

Robertson's chemical reaction model is a famous finding by HH. Robertson in 1966 re­lated to kinetic reaction of chemical reactants. It describes chemical reaction with three main reactants involved which are reactant A, B and C. The reaction rates involved are three dif­ferent values and largely different from each other. The model proposed is a system of three non-linear equations and it is widely known as a stiff problem. Numerical experiment of im­plicit Backward Differentiation Formula (BDF) method are adopted computationally to explain the performance of the method in solving stiff problem. The result shows performance of the method in term of computational time and number of iteration used.
