Chemical Equilibrium | Kemi Rapport på Engelsk

Rapporten er skrevet på engelsk.

Indholdsfortegnelse
a) Introduce the chemical equilibrium that you used for the experiment. Why is it useful? Write the equilibrium expression.
b-g) Explain the stress that you put on the equilibrium in each of the test tubes 1-6. What were your macroscopic observations? How do you explain your macroscopic observations using Le Chatelier’s principle and how do you explain them using mathematics and the equilibrium expression?
Test tube 1:

Uddrag
We add Fe 3+ ions to the equilibrium mixture, which means an increase in reactants. In order for Q to reach K again, some of the reactants are turned into products which means a favor in reactions towards products. Because of more products, the solution will turn darker. An increase in the denominator means that Q would lower. So, to balance it out the numerator increases as well. So when the reactants are turned to products the denominator is lowered and the numerator is increased.
