3.4 Reacting quantities Flashcards
1
Q
what is the theoretical yield?
A
the maximum possible amount of product produced
2
Q
why is the actual yield normally less than the theoretical yield?
A
reaction may not have completed
other reactions may have occurred alongside the main reaction
some product may have been lost in the reaction
3
Q
percentage yield =
A
actual yield/theoretical yield *100
4
Q
what is the limiting reagent?
A
the reactant which is fully used up in the reaction
SO
the reactant not in excess
5
Q
what are all calculations based on?
A
the limiting reactant
6
Q
why is a high atom economy useful?
A
produces a large proportion of desired products and less waste product
makes the best use of natural resources
