Limiting & Access

Question 1

In industry there is what

Answer 1

A more expensive cost of reactants than the other

Question 2

What do chemsitry want to ensure

Answer 2

All more expensive reactant react in order to minimise waste and reduce

This is achieved by using more then what’s required of the less expensive reactant

Question 3

What will it mean if the less expensive reactant is used

Answer 3

This means some of this reactant leftover is here for this reactant is said to be in excess of

Question 4

What will happen to the other reactant

Answer 4

It will react completely being entirely used up and the reaction will stop

This is said to be the limiting reactant as it limits the amount of products that can be fomed

Question 5

The limiting reactant can do what

Answer 5

Calculate how much product will be formed

Question 6

What other thing can the limiting reactant do

Answer 6

Limit how much product can be formed

Question 7

To find out which reactant is excess what must we do

Answer 7

Work out the number of moles each reactant and use a balanced chemical equation
