Question 5 1 pts

What is the correct interpretation of an 85% yield for a given reaction?

85% of the anticipated amount of products were produced (relative to the theoretical yield)

O 15% of the reactants were used up

O 85% of the reactants were used up

15% of the anticipated amount of products were produced (relative to the theoretical yield)

True or false: The limiting reactant is the reactant that is used up after the reaction is complete.

O True

False

a) 85% of the reactants were used up

b) True

Explanation:

Percentage yield is defined as the ratio of actual yield to theoretical yield in terms of percentage. The actual yield is the amount of product obtained after the experiment and the theoretical yield is the amount of ideal product that should have been obtained.  

Formula :  

Thus 85 % yield means 85 % of the reactants were used up to give only 85% of products.

The limiting reactant is the reactant that limits the amount of product formed and hence is completely used up after the reaction is complete. Thus the given statement is True.
