12. Thermodynamics and Kinetics of Transformation
Reactions
Transformation Reactions of Organic
Compounds1. Several different reactions by
which the organics can be transformed2. Reaction
products3. Reaction kinetics4. Important
environmental variables influencing- fast rate
vs. slow rate equilibrium vs. kinetic aspects-
Simplest approach for modeling one-box or
well-mixed reactor
