Limiting reactant Flashcards
1
Q
how do you get a theoretical yield?
A
by getting the limiting reactant qty
2
Q
steps to get limiting reactant
A
- identify what you have
- change given values to moles of desired values
- identify smallest = LR
- ER = the other
3
Q
LR
A
limiting reactant
4
Q
ER
A
excess reactant
5
Q
find out what is left over ?
A
find excess by finding what is used for excess & subtracting that from the beginning value of that substance
6
Q
Reaction yield (percent error) formula
A
% yield = actual yield/ theoretical yield X 100
7
Q
theoretical yield definition
A
max possible yield calculated
8
Q
actual yield definition
A
Experimental yield found
