Chapter 14 Chemical Kinetics
www.sas.upenn.eduChemical Kinetics Chemical kinetics: the area of chemistry dealing with the speeds or rates at which reactions occur. Rates are affected by several factors: • The concentrations of the reactants: Most chemical reactions proceed faster if the concentration of one or more of the reactants is increased.
Fundamentals of Chemical Reactor Theory1
www.seas.ucla.eduChemical kinetics and reactor engineering are the scientific foundation for the analysis of most environmental engineering processes, both occurring in nature and invented by men. The need to quantify and compare processes led scientists and engineers throughout last century to develop what is now referred as Chemical Reaction Engineering (CRE).
