Chemical Reaction Engineering I

Chemical Reaction Engineering I, Kinetics of Homogeneous Reactions, Reactor Design.

  • Defining a rate equation and its representation, single and multiple reactions, elementary and nonelementary reactions, molecularity, and order of reactions, kinetic models for non-elementary reactions, searching mechanism, rate-controlling step. Introduction, conversion of mass in reactors, performance equation for ideal stirred tank reactor, tubular flow reactor, batch reactor, space-time, and space velocity. Isothermal Reactors for single Reactions: Batch reactor, mixed versus plug flow reactors, second-order reactions, graphical comparison, multiple reactor system, plug flow reactors in series and in parallel, equal size mixed reactors in series, reactors of different types in series, recycle reaction (flow, batch), auto-catalytic reactions, non-steady flow semi-batch reactors. Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is to be contrasted with thermodynamics, which deals with the direction in which a process occurs but in itself tells nothing about its rate. To understand the kinetics of chemical reactions, and the factors that affect kinetics, we should first examine what happens during a reaction on the molecular level.
  • There are four main factors that can affect the reaction rate of a chemical reaction:

    1. Reactant concentration

    2. Physical state of the reactants and surface area

    3. Temperature

    4. Presence of a catalyst.
