Chemical Engineering of Heterogeneous Reactions

This lecture covers the observed rates of chemical reactions in heterogeneous systems, focusing on the impact of internal mass transfer. The instructor explains the calculation of observed rates for different geometries, such as spheres and cylinders, and discusses the effectiveness factor in reaction kinetics. The lecture delves into the Arrhenius equation, heat transfer effects, and the material and energy balances in isothermal pellets. Detailed calculations and considerations for endothermic and exothermic reactions are also explored.
