Description
Lecture 10 (1/30/13) • Chemical Equilibrium: o A dynamic process in which concentrations of reactants and products  remain constant over time. o Rate of a reaction in the forward direction matches its rate in the reverse  direction. • When→and ←  Reaction Rates are Equal: o Reaction:  2 NO(g) ⇌ N 2 4g) o From experimental data:  Ratef= kf[NO 22  Rater= kr N2O4]2 o At equilibrium:  f [NO2]  =r  [2 4 ]  Rearrange: k f = [N 2 4 ]=constant, K k 2               [NO 2] • Equilibrium Constant: o Equilibrium Constant Expression:  Ratio of equilibrium concentrations or partial pressures of products  to reactants, each term raised to a power equal to the coefficient of  that substance in the balanced chemical equation.  2 NO(g) ⇌ N 2 4g) [N2O 4] K = [NO ]2    2 o Equilibrium Constant:  The value of K at a specifi
