Quantitative Analysis - Paper 1 Flashcards
1
Q
Define theoretical yield
A
Theoretical yield is the maximum possible mass of a product that can be made in a chemical reaction.
2
Q
Define actual yield
A
An actual yield is the mass of a product actually obtained from the reaction.
3
Q
Define percentage yield
A
Percentage yield is actual yield as a percentage of theoretical yield.
4
Q
Explain why the actual yield tends to be less than the theoretical yield.
A
- Incomplete reactions.
- Practical losses during the experiment.
- Competing, unwanted reactions (side reactions).
5
Q
Define atom economy
A
Atom economy is the total Mr of all desired products as a percentage of that of all reactants.
6
Q
What is the molar volume at r.t.p.?
A
24dm3
