C4.4 - The Yield Of A Chemical Reaction (Finished) Flashcards
1
Q
What is the equation for % yield?
A
Mass of product actually made / maximum theoretical mass of product * 100
2
Q
What does the % yield of a chemical reaction tell you?
A
How much product is made compared with the maximum amount that could be made
3
Q
What factors affect % yield?
A
- product being left behind
- reactions not completing
- unexpected reactions
- losses from separating products from mixture
- the reaction may be reversible, it will reverse
- Impure reactants
4
Q
Why should industrial processes have a high % yield?
A
To reduce waste and costs
5
Q
