Atom economy and percentage yield Flashcards
1
Q
What is atom economy?
A
the atom economy of a reaction is found directly from the balanced equation
tells us in theory how many atoms must be wasted
% atom economy = mass of desired product / total mass of reactants x 100
2
Q
What is % yield?
A
tells us the practical effiency of the process
how much is lost by the process of obtaining a product and a result of reactions that do not go to completetion
3
Q
What is the equation for % yield?
A
number of moles of a product / theoretical maximum number of moles x100
