What are Chemical Kinetics? Chemical Kinetics Kinetics - how fast does a reaction proceed? Thermodynamics - does a reaction take place? Reaction speed: measured by the change in concentration with time. Important factors which affect rates of reactions: reactant concentration temperature action of catalysts surface area 2. What is chemical kinetics. 3. Reaction Rates Rate of a chemical reaction = change in concentration (mol/L) of a reactant or product with time (s, min, hr); Rate of Reaction=. 4. Chemical Kinetics A B ∆ [A] rate = ∆t ∆ [A] = change in concentration of A over time period ∆t ∆ [B] rate = ∆t ∆ [B] = change in concentration of B.

Chemical Kinetics is the study of the rate at which a chemical process occurs. Besides information about the speed at which reactions occur, kinetics also sheds light on the reaction mechanism (exactly how the reaction occurs). Physical State of the Reactants In order to react, molecules must come in contact with each other.

Chemical Kinetics Outline: Kinetics Reaction Rates How we measure rates. Rate Laws How the rate depends on amounts of reactants. Integrated Rate Laws How to calc amount left or time to reach a given amount. Half-life How long it takes to react 50% of reactants. Arrhenius Equation How rate constant changes with T. Mechanisms Link between rate and molecular scale processes. Chemical Kinetics The study of reaction rates; How fast does a reaction proceeds and what factors affecting it; A measure of the change of the concentration of a reactant (or a product) as a function of time. The study of rate yields information on the mechanism by which a reaction occurs at molecular level. Types of Rates Initial Rates Rates.
