Rate Of Reaction (1)

Question 1

Label the laboratory apparatus needed to measure the rate of reaction producing a gas

Answer 1

Gas syringe

Flask

Question 2

Explain why a reaction stops

Answer 2

Because one if the reactants is all used up

Question 3

What does the rate of reaction measure?

Answer 3

How much product is formed in a fixed time period

Question 4

Understand common units for the rate of reaction

Answer 4

g/s or g/min

Cm³/s or cm³/min

Question 5

Explain in terms of reacting particles, why the amount of product formed is directly proportional to the amount of limiting reactant used

Answer 5

The amount of the limiting reactant you start with dictates the amount of product you will make. When there are more reactant particles, there is more reaction and more product particles produced.

Question 6

What is the limiting reactant?

Answer 6

The reactant not in excess that is all at the end of the reaction

Question 7

What is the amount of product formed directly proportional to?

Answer 7

The amount of product formed is directly proportional to the amount of limiting reactant used

Question 8

Recognise that some reactions can be fast others can be slow

Answer 8

Rusting is a slow reaction

Burning and explosions are very fast reactions
