Coenzymes are small, organic, non-protein molecules that bind only for a short period of time to the active site just before or with the substrate. They take part in the reaction and get changed in some way. Then they're recycled back into the reaction again.

Cofactors are inorganic and combine with the enzyme or substrate making the enzyme-substrate complex  form more easily, because it affects the distribution and in some cases the shape of enzyme-substrate complex.

I hope this help! :-)
