Step 1 of 3

Chemistry II Notes – Week 5 Ch. 16: Chemical Equilibrium  Dynamic equilibrium o Both sides of a chemical equation are happening at the same rate  Equilibrium constant o K o K is unitless o Ratio of products and reactants at equilibrium o Changing the concentration of anything changes everything o Law of mass action c d a b  K = [C] [D] / [A] [B]  aA+bB↔cC+dD o K is products over reactants o Reciprocal of reverse reaction  As product concentration increases, the reverse reaction rate increases o At equilibrium, concentrations are constant  Reactants and products aren’t necessarily equal in amount  There can be product or reactant favored reactions  When K is greater than one o Product favored reaction o Less reactants used  When K is less than one o Reactant favored reaction o Less product remaining  For gases o K p P xcP dd/ Paax P b o Partial pressures in atm o K p K xc(RT) Δn  Delta n is the change in moles between reactants and products  If it is zero then P will equal Kc  Heterogeneous Equilibrium o Liquids and+solids don-t count o H 2(l) ↔ H (g) + OH (g)  K c [H ][OH ] -
