8. the equilibrium constant Flashcards
1
Q
what does Kc tell you
A
how far right or left the equilibrium is
2
Q
conditions for Kc
A
must be a homogeneous reaction
must have reached dynamic equilibrium
3
Q
expression for Kc
A
aA + bB dD + eE
Kc= [D]d[E]e / [A]a[B]b
(products/reactants)
4
Q
Kc varies with
A
temperature
5
Q
if Kc is greater than 1
A
there are more products than reactants
equilibrium lies to right
(higher above 1, further to right)
6
Q
if Kc is less than 1
A
more reactants than products
equilibrium lies to left
(further below 1, further to left)
