Document Summary

Lecture 8: calculating k and application of equilibrium constants. Aa + bb = cc + dd. Q c = [c] c [d] d / [a] a [b] b = k. G = rxn g o + rt ln( [c] c [d] d / [a] a [b] b ) Changes to concentration, temperature, & pressure can disturb equilibrium. If external stress is applied to system @ equilibrium (t, p, composition, etc. then system adjusts to minimize the change & reach a new equilibrium. Increase in reactants = equilibrium shifts to the right. Increase in products = equilibrium shifts to the left. Treat heat (t) as species in rxn. Increase in heat, equilibrium shifts to left. Decrease in heat, equilibrium shifts to right. K is function of t - k changes. System response when pressure or volume changes. Increase p of reactants, equilibrium shifts right. Increase v of reactants, equilibrium shifts left.
