23.3 Catalysis Phase and physical state A phase is a region of space, throughout which all physical properties of a material are essentially uniform Examples of phases: Heterogeneous catalysis Heterogeneous catalysis involves the use of a catalyst which is...
23.2 Reaction Mechanisms Rate-determining step In any chemical change, some bonds are broken and new ones are made. Quite often, these changes are too complicated to happen in one simple stage. Instead, the reaction may involve a series of small changes one...
23.1 Orders of Reaction and Rate Equations Rate Equation The rate of reaction is dependent on the concentration of the reactants. Doubling the concentration may double or triple the rate of reaction, just to name a few A rate equation shows this...
CHAPTER 23: Reaction Kinetics Orders of Reaction and Rate Equations Reaction Mechanisms Catalysis Learning outcomes: explain and use the terms: rate equation, order of reaction, rate constant, half-life of a reaction, rate-determining step construct and use...
