this is so good saved my gcse (learning everything the day before)

[biyapoo]

revising for my test tomorrow on rate of reactions, reversible reactions, equilibrium and la chatelier's principle. wish me luck..

00:08 Reversible reactions and equilibrium

00:53 Ammonia and hydrogen chloride can combine to form ammonium chloride in a reversible reaction.

01:38 At equilibrium, the forward and backward reactions occur at the same speed.

02:23 Concentrations of reactants and products at equilibrium can vary.

03:06 The position of equilibrium can change depending on the conditions.

03:48 Reversible reactions reach equilibrium in a closed environment.

04:32 Heating hydrated copper sulfate drives the reaction to the right, evaporating off the water

05:14 Reversible reactions and equilibrium
