Amount of a substance: Percentage Yield

Question 1

Why do we rarely achieve the maximum theoreitcal yield for a chemical reaction?

Answer 1

= not all of the reactant react- reversible reactions
= side reactions= bi products
= some product could be lost

Question 2

What is the equation for percentage yield?

Answer 2

= percentage yield
= Yield/ maximum theoretical yield
x 100
= can either be in grams or moles

Question 3

What is percentage yield?

Answer 3

= How much reactant of an reaction actually formed the product
= rarley 100%
