A
kp (1/RT)^delta n
2
Q
Calculating the equilibrium constant from measured equilibrium concentration
A
- write out the formula
- make an ICE table with the initial molarities.
based on one of the equilibrium concentrations calculate the rest based on stoichiometry - plug into the equilibrium consent formula
3
Q
reaction quotient
A
[C]^c [D]^d/[A]^a [B]^b
4
Q
When Q> K
A
reactions runs to the left
5
Q
when Q < K
A
reaction runs to the right
6
Q
Q = K
A
the reaction is at equilibrium
7
Q
finding the equilibrium concentration form the equilibrium constant and initial concentration or pressures
A
- set up and ice box with initial concentration
- Calculate the reaction quotient using the initial concentration. Compare the answer to see which direction the reaction proceeds. Which ever way the reaction proceeds add x there
- plug the final equilibrium into the equilibrium equation and solve for x
