MP3 Common Assessment Week 7

The limiting reactant

• slows the reaction down
• is used up first
• is the reactant that is left over
• controls the speed of the reaction

When does a chemical reaction stop?

• When the lab is finished

• When the excess reactant is used up

• When all the limiting reactant is used

• Chemical reactions never stop

The limiting reactant in a chemical reaction will-

• determine the minimum mass formed of any product in the reaction

• determine the maximum mass formed of any product in the reaction

• not be finished during the reaction

• be part of the products

True or False?

A chemical reaction stops before the limiting reagent is used up.

• True

• False

The amount of product formed is dependent on...

• the reactant that will be leftover at the end of the reaction.

• the reactant that is used up at the end of the reaction.

• neither the reactant that will be leftover nor the reactant that is used up at the end of the reaction.

• the other product (if there is another)
