Equilibrium

Equilibrium

A reversible reaction is where the products of the reaction can themselves react to produce the original reactants.

In other words: A+B <==> C+D or A and B react to produce C and D

                                                                 C and D react to produce A and B

                                                                                                                             Easy.

Also Fairly Easy:-

                                       When A and B react their concentrations fall, (think about it, there's less of them because they're being used in reactions) so this means a lower reaction rate, a slower forward reaction. However, as A and B have been reacting into C and D there is now a higher concentration of them. C and D react to form A and B faster, due to the high concentration and there is a faster backward reaction. 

After a while...

                        Eventually this balances and the reaction rates equal one another, this is equilibrium (did you guess it from the name?). This leaves no overall…
