5.51 - The yield of a reaction Flashcards
1
Q
What are 3 reasons for the mass of a product being less than the maximum possible?
A
- The reaction is reversible, so may not be complete
- There are side-reactions that form other products
- The product may need to be purified, which would result in a loss of product
2
Q
What is theoretical yield?
A
The maximum amount of product that could be formed from a reaction, using set amounts of reactions
3
Q
What is actual yield?
A
The actual amount of product formed
4
Q
How do you calculate percentage yield?
A
(Actual Yield / Theoretical Yield) * 100
5
Q
What units are used for yield in the laboratory?
A
Grams
6
Q
What units are used for yield in industry?
A
Kilograms and turns
