Percentage Yield And Sustainable Development

Question 1

What is a reversible reaction?

Answer 1

When the products of the reaction can themselves react to produce the original reactants

Question 2

Give an example of a reversible reaction …

Answer 2

Ammonium chloride = ammonia + hydrogen chloride

Question 3

What will it mean for the overall yield if a reversible reaction occurs?

Answer 3

A lower yield

Question 4

‘In a reversible reaction the reactants will never be completely converted to products’ why?

Answer 4

Because the reaction goes both ways

Question 5

What may happen if filtration is used in a reaction?

Answer 5

some of the product may be lost when it’s separated from the reaction mixture

Question 6

Unexpected reactions can use up the reactants, causing what?

Answer 6

Not much reactant left to make a desired product

Question 7

What is sustainable development about?

Answer 7

Making sure we don’t use resources faster than they can be replaced

Question 8

What are the three reasons that yields can’t be 100%?

Answer 8

The reaction is reversible
Filtration
Unexpected reactions
