Equilibrium Reactions

Irreversible Reactions – reactions that has products that cannot turn back into their reactants.

Reversible Reactions – reactions that has products that can react back into the original reactants.

Dynamic Equilibrium – when there is no overall change in the amount of products and reactants even though the reaction is ongoing. Dynamic Equilibrium can only take place in a closed system. The position of dynamic equilibrium is not always at a half-way point, as in it may be at a position where there are more products than reactants.

Le Chatelier’s principle – if a closed system at equilibrium is subject to a change then the system will adjust in such a way as to minimise the effect of the change.
