Effects of altering a concentration in chemical equilibria

Powerpoint

Start with a thought experiment

Based on the model, a well-founded hypothesis can be drawn up that needs to be tested.

You will find a worksheet describing the experiment here. But at the moment there is only one German variant, sorry.

Changing the temperature has effects on constant "K" and you will get a "new equlibrium". Changings in pressure (or concentrations) lead to a reestablishment of the equilibrium.
