# Chemistry: Kinetics and Equilibrium

We have 15 ready-to-use problem sets on the topic of kinetics and equilibrium. These problem sets will focus on the methods used to determine the factors that affect the rate of a reaction and upon the use of an equilibrium constant to determine the equilibrium position of a reversible reaction system. Problems will range from the very easy plug-and-chug to the more difficult analysis of multi-step problems.
