Part 1: Calculating Kc:
Example mixture A:
6.55 cm3 0.5M NaOH neutralised the mixture
For the equilibrium:
|
|
|
HCl |
|
|
|
CH3COOH |
C2H5OH |
à |
CH3COOC2H5 |
H2O |
Remember:
Kc = |
[Products] |
|
[Reactants]
|
|
Kc = |
[CH3COOC2H5]
[H2O] |
[CH3COOH] [C2H5OH] |
You are after the equilibrium
concentrations.
These can be worked out from the starting
moles and an equilibrium mole value.
