Define a reversible reaction.

A reversible reaction is one in which the products react to give back the reactant, i.e. the reaction is going in both directions

Define chemical equilibrium.

Chemical equilibrium is a state of dynamic balance in a reversible reaction where the rate of the forward reaction is the same as the rate of the backward reaction

Define a dynamic state

In a dynamic state the reactant are continuously forming products and the products are continuously forming reactants

Define dynamic equilibrium.

In a dynamic equilibrium the rate of the forward reaction is equal to the rate of the backward reaction

State Le Chatelier's Principle

Le Chatelier's principle states that if a stress is applied to a system at equilibrium, the system re-adjusts to relieve the stress applied

What does Le Chatelier's Principle predict will happen in an all-gaseous reaction if there is an increase in pressure?

Le Chatelier's Principle predicts that in an all-gaseous reaction an increase in pressure will favour the reaction that brings about a reduction in volume, i.e. it will shift towards the side with the smaller number of molecules

What does the equilibrium constant equal?

Kc = [C]^c [D]^d / [A]^a [B]^b
