Document Summary

Equilibria, acids & bases: equilibria (sections eg 14. 1-14. 7) Le chatelier"s principle: acids, bases and ph (sections eg 15. 1-15. 8) A + b c + d complete. Rate of forward rxn = rate of reverse. A + b c + d dynamic. In a closed sealed vessel at 850 pressure of co2 = N2o4(g) to no2(g) is exactly balanced by the rate of association of 2 no2(g) to n2o4(g) The net effect is that there is no change in the concentration of either n2o4(g) or no2(g) as defined by our being of equilibrium. Ratio of reactants and products does not change. Refers to a particular reaction equilibrium under defined conditions. Eab-4 aa(g) + bb(g) cc(g) + dd(g) K = [h2] + [i2] / [hi] [hi] = [h2] + [i2] / [hi]2 for n2(g) + 3h2(g) 2nh3(g) Concentration term for solids and liquids is ignored. The concentration of a pure solid is constant. The concentration of a pure liquid is constant.
