Reaction kinetics and chemical equilibria. The concept of equilibrium and how to predict where the equilibrium is shifted for chemical systems. The pH concept the way we use to describe relative acidities of aqueous solutions . Buffers a way to control acid-base equilibrium. Factors that affect the reaction rates Chemical nature of the reactants .
Some compounds are more reactive than the others.
Physical state of the reactants . Homogeneous reactions generally go faster than heterogeneous. Concentration of the reactants. X Y Reaction is fast at the beginning but slows down as it proceeds. Chemical compounds that are able to accelerate chemical reactions without themselves being changed are called catalysts .
