1C.4 The Yield of a reaction Flashcards
1
Q
what is the theoretical yield
A
is the predicted amount of product
2
Q
what is the actual yield
A
is usually less than the predicted yield and is the amount of product you have.
3
Q
what is the % yield
A
compares the actual yield with the theoretical yield.
4
Q
what is the limiting factor
A
It is the reactant that is completely used in the reaction and it determines the theoretical yield
5
Q
why dont we get 100% yield
A
- Incomplete reactions:
- Unwanted reactions/competing reactions:
- Some of the product may be left in the container
- It may be difficult to purify the product
- Reactants may be impure
- the reaction might be reversible
