This is a series of videos introducing kinetics and equilibrium at the Pre-AP level. Rate law expressions are determined from experimental data in which ratios of experiments are used to determine the order with respect to each reactant. Examples are limited to those with whole number, positive orders (including zero order). The value of the rate constant, k, is determined (including units). The idea of a dynamic equilibrium is introduced and an equilibrium constant expression is set up for a variety of reaction types. Acid and Base equilibria are used as examples of solving equilibrium systems using “RICE” tables (reaction, initial, change, equilibrium). The magnitudes of equilibrium constants are used to compare the strength of acids and bases. The effects of a “stress” on an equilibrium system are predicted using LeChatelier’s Principle.
