1

The mass that would be achieved if every single atom in the reaction reacted
2
Q
State 4 reasons why theoretical yield is hardly ever achieved?
A
-Not all the reactants are used up
-Products are lost
-Other products created due to unexpected side reactions
-Reversible reaction
3
Q
Define ‘ yield ‘
A
Actual amount of product obtained
4
Q
Define ‘ percentage yield ‘
A
Amount of product obtained compared to maximum theoretical amount
5
Q
State how to calculate percentage yield
A
% yield = Actual yield / Theoretical yield x 100
6
Q
What is percentage yield always between?
A
0% and 100%

Q
What does 100% yield mean?
A
You got all the product you expected to get
