6669026047Reaction RatesCalculating Rate: change in concentration/ change in time (basically it's slope) Control Factors: Concentration, physical state, temperature, catalysts If collision increases, so does reaction rate Given: aA+bB= cC+dD, then rate: (see picture)65
6669026048Rate Law and TemperatureAs temperature increases, the value of K increases. k= rate constant R: energy gas constant (8.31) A: collision frequency factor Ea: Energy of Activation66
6669026049Endothermic vs. ExothermicEndo: Heat absorbed H>0 Exo: Heat released H<067
6669026050CatalystsLowers energy of activation, which increases the rate constant (k) and thus increases rate of reaction of both forward and reverse reactions Yields products more quickly, but the same amount of product68
6669026051Equilibrium ConstantReactant favored: K<1 Product Favored: K>169
6669026052Reaction QuotientAt equilibrium, K=Q If QK, system is past equilibrium, more products than reactants. Will head left70
6669026053Disturbing a Chemical Equilibrium3 ways to disturb equilibrium: 1. Changing temperature 2. Changing concentration of a reactant 3. Changing volume (for systems involving gases)71
6669026054Ka and PkaAs Ka decreases, Pka increases As acidity increases, Ph decreases72
