Ch 15 Rates of Chemical Reactions

Ch 15 Rates of Chemical Reactions. Chemical Kinetics is a study of the rates of chemical reactions. Part 1 macroscopic level what does reaction rate mean? how are reaction rates determined experimentally? how do factors like temp and conc influence rates?

Thermodynamics

Thermodynamics. Tells if a reaction will occur. Kinetics. Tells how fast a reaction will occur. Reaction Rate. Speed of the reaction. Found experimentally. Measure change in concentration of a reactant or a product over time. Rate = ?Conc ?time. How do you measure rates?.
