Chemistry Chapter 14

1
Equilibrium applies to the -------- of a reaction, ----------
- extent
- the concentration of product that has appeared after an unlimited time, or once no further change occurs.
A system at equilibrium is ------------

dynamic on the molecular level; no further net change is observed because changes in one direction are balanced by changes in the other
the relationship between the chemical equation and the concentrations of reactants and products is called

the Law of Mass Action
Equation relationship

K=([C]^c x [D]^d)/([A]^ax[B]^b)
when 4 NO₂is put into equilibrium constant expression, its displayed as

[NO₂]⁴
when the reaction is written backwards, the equilibrium constant is

inverted
------------don’t count in the equilibrium equation

Solids
A larger K value means

more product available
(Q = K) mean

the system has come to equilibrium
