2.3 The effect of changing conditions on equilibria

HideShow resource information
What is Le Chatelier's principle?
When a system at equilibrium is disturbed, the equilibrium moves in the direction so as to reduce disturbance.

How do catalysts affect Kc?
They have no effect as they affect forward and backward reactions equally.
2 of 6
If Kc is bigger than 1, are there more reactants or products?
Products.
3 of 6
How does increasing the number of reactants affect Kc?
Kc increases.
4 of 6
How would a decrease in temp in exothermic reaction affect Kc?
Kc increases.
5 of 6
