Chapter 13

Chemical equilibrium exists when two opposing processes occur at equal rates. An equilibrium position is a set of equilibrium concentration. The symbol >> means MUCH greater then.

EXAMPLE: If at a given temp. the equilibrium constant for the reaction (H2)g + (Cl2)g --> 2NH3g is Kp, then the equilibrium constant for the reaction HCl g  -->  <-- 1/2 H2 (g) + Cl2 (g) is ?                       1                                                        ----                                         the square root of kp
