Unit 7 Flashcards
equilibrium
rate foward reaction= rate reverse reaction
K =
[products] / [reactants]
concentrations at equilibrium are
constant
K + Q never involve
solids or liquids
Q works
at anytime
K works
only at equilibrium
only ____ can change K
Temperature
Q=K
equilibrium
Q>K
more products(shift to the left)
Q<K
more reactants (shift to the right)
K> 10^4
goes to completion
-large K value a lot of products
K<10^4
no rxn
-small k value little amount of products
what does adding a different gas do to equilibrium?
does not shift it
Le chateliers
Ksp< 1
insoluble more reactants
Ksp>1
soluble more products
common ion
same ion in a solution
-reduces solubility
when there is a pressure increase…
reaction will shift towards the side with less mols
addition of reactants means…
addition of products
to establish equilibrium
addition of one reactant means…
more of the other reactant
do catalysts have effect on equilibrium?
No
