Chemical Kinetics

Chemical Kinetics. The Study of Reaction Rates. Chemical Kinetics. Kinetics involves the study of several factors that affect the rates of chemical reactions. The final goal is to use all of the data to develop a step-by-step reaction mechanism .

Thermodynamics

Thermodynamics. General Information. "Thermodynamics" , is the study of the energy changes or transfers accompanying physical and chemical processes helps us predict whether a rxn will occur under certain conditions DO NOT ASSUME THAT ALL REACTIONS HAPPEN AUTOMATICALLY!. Spontaneity.

Equilibrium

Equilibrium. Equilibrium. Many reactions can proceed in both the forward direction (towards products- to the right) and the reverse reaction (towards reactants- to the left) Recall weak acids and bases!. Dynamic Equilibrium.

Gas Equilibria

Gas Equilibria. The Jungle Begins. Reaction is reversible Both products and reactants are present Forward and reverse reactions take place at the same rate BUT the partial pressures must be specified. For the reaction 2A = B. What is Equilibrium?. Using the K eq constant.

Heterogeneous Equilibria:

Heterogeneous Equilibria: A homogenous reaction is one in which all the substances are in the same state. A heterogeneous reaction is one in which all the substances are not in the same state. CaCO 3 (s) CO 2 (g) + CaO (s) Calcium carbonate carbon dioxide lime.

EQUILIBRIUM LAW

EQUILIBRIUM LAW. When you use concentration data to FIND OUT whether you can get a constant value by manipulating it, you are finding Q, the reaction quotient. E.g. 2HI ? H 2 + I 2 These are all Q values. These constant values indicate the equilibrium law.
