Chemistry 112 – Day 6 (09/16/2019) Chapter 12 – Kinetics o The study of kinetics explores the rate or a reaction o How fast does it go? In contrast to equilibrium which answers how far does it go o By looking at how fast a reaction goes and how its rate changes with certain variables, we can propose rate mechanisms. Reaction Rate o Change in relation to time o For chemistry we usually use the change in conc. Of something over a certain time period. o Rates by convention are always expressed as a positive value. o 4 general factors that we can control to manipulate the rate of a chemical reaction. Influencing the Rate o Concentration o Physical State o Temperature o Catalysts Expressing the Rate o Reactant concentrations decrease while product concentrations increase For A B o Rate of reaction = - Change concentration of A Change Time = - conc A 2 Conc A 1 t 2 t 1 Δ ( conc A ) Δt o How would you express this in terms of the product?
