Equilibrium is when the products that are being made, are done at the same rate as the products spliting back to the reactants.

Equilibrium is a state when the concentration of reactants and products don't change. The relative amounts of the reactants at equilibrium depend on the conditions of the reaction. 

I'm guessing the thing that you're looking for is applied with C7, you also need to know about dynamic equilibrium, (which is only achieved in a closed system) it happens in reversible reactions, neither the forward or backward reaction are complete as both reactants and products are present, once it is achieved the concentration doesn't change. Once in dynamic equilibrium it would appear that the reaction has stopped when infact the rate of reaction on both sides are going at the same rate (it's like running on a treadmill even though you're running and the treadmill is rolling back you're still at the same place.) It can be used to describe the difference between strong and weak acids.

I know thats a lot to take in, but I really hope it helps.

Wow, thankyou so so so so much. Both these answers have been so much help. And, yes, I need to know about dynamic equilibrium too so thankyou for explaining that as well! Hopefully I will be able to answer a question about it tomorrow in the exam.. :D
