Atom Economy And Percentage Yield Flashcards
1
Q
What is the theoretical yield?
A
The mass of product that should be made in a reaction if no chemicals are lost in the process.
2
Q
What is the atom bomb economy of a reaction?
A
The measure of the proportion of reactant atoms that become part of the desired product in the balanced chemical equation
3
Q
How do you work out the atom economy of a reaction?
A
Molecular mass of desired product / sum of molecular masses of all products , X 100
4
Q
Why is it important to develop reactions with high atom economies?
A
- Companies in the chemical industry will often choose to use reactions with high atom economies. It has environmental and economic benefits. Better atom economies are more sustainable and more efficient.
5
Q
How do you work out percentage yield?
A
Actual yield divided by theoretical yield , X 100
