When you are preparing aspirin why might the yield be lower than predicted and why might the yield be higher than predicted ? Also, why does the mass of aspirin increase after recrystallisation ?
I really need help to answer these questions for my lab report ...

Impure reactants/exothermic and thus high energy will be wasted/reversible reaction.
Yield may be higher: reactants have fully decomposed, more energy released? Sorry Im so bad I know
