Physical and Chemical Equilibrium, Equilibrium Law, Le Chatelier's Principle

• Equilibrium results from equal and opposite rates of chemical or physical processes

• Learn equilibrium law for general reaction aA + bB = cC + dD

• Write equilibrium law expressions for several chemical and physical systems

• Connection between K_c and K_p for gas equilibria

• Calculate equilibrium compositions of systems given K and starting mixture

• Le Chatelier’s principle: if P increases system reacts to fewest no. of gas moles; if reagent added system reacts to consume it; if T increases the endothermic direction is favored
