Kinetics addresses the speed of a reaction, the change in product concentration (or reactant concentration) per unit time.
Equilibrium addresses the extent of a reaction, the concentration of product that results given unlimited reaction time.
At equilibrium: rateforward = ratereverse
A system at equilibrium is dynamic on the molecular level; no further net change in reactant and product concentrations is observed because changes in one direction are balanced by changes in the opposite direction.
