7.1 Equilibrium
Le Chatelier's Principle
when a system at equilibrium is subjected to aa change, it will respond in such a way as to minimize the effect of the change
change in concentration
addition of reactant cause system to respond by removing reactant (favor forward reaction; shift equilibrium to the right)

-
addition of catalyst
do not change position of equilibrium or yield of single reaction, but enable equilibrium to be achieved more quickly
Equilibrium
Features
-
-
-
-
1) is dynamic
reaction has not stopped but both forward and backward reactions are still occurring at the same time

-
reaction quotient Q
Q = measure of the relative amounts of reactants/ products present in a reaction at a particular time; value determined from substitution of conc. of reaction components measured at same time into equilibrium expression
as reaction continues, Q value changes in direction of Kc; enables prediction of direction in which reaction will proceed
