1
Q
Write the equilibrium constant for this formula:
jA + kB –> lC + mD
j, k, l, m are coeffecients
A
K= [C]^l * [D]^m / [A]^j * [B]^k
2
Q
If K>1…
A
the reaction favors products
3
Q
If K<1…
A
the reaction favors reactants
4
Q
If K=1…
A
equilibrium lies in the middle
5
Q
How do you determine if a reaction is at equilibrium?
A
- Use the equilibrium constant formula and fill in the values
- Solve equation
- Compare answer to Keq value given
6
Q
If Q>Keq, reaction goes where?
A
to the right (NOT at equilibrium)
7
Q
If Q<Keq, reaction goes where?
A
to the left (NOT at equilibrium)
8
Q
What happens if Q=Keq?
A
The reaction is at equilibrium
