A variational formulation of a chemical problem can be very useful because special solution methods can be used, and it gives a deeper insight into the structure, for example, of diffusion reaction. In this study, a variational theory is established for coupled diffusion and nth‐order reaction in a spherical catalyst pellet. Various variational approaches can be applied to obtain both analytical and numerical solutions.
