Flashcards in Rate Of Reaction (1) Deck (8):
1

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

Gas syringe
Flask

2

Explain why a reaction stops

Because one if the reactants is all used up

3

What does the rate of reaction measure?

How much product is formed in a fixed time period

4

Understand common units for the rate of reaction

g/s or g/min
Cm³/s or cm³/min

5

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

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.

6

What is the limiting reactant?

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

7

What is the amount of product formed directly proportional to?

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

8

Recognise that some reactions can be fast others can be slow

Rusting is a slow reaction
Burning and explosions are very fast reactions
