C3 - Rates of reaction Flashcards
1
Q
What is rate of reaction?
A
Rate if reaction is the amount of product formed in a fixed time.
2
Q
What is the limiting reactant?
A
The reactant used up by the end of reaction.
3
Q
What is the relationship between amount of product and reactant used?
A
It is directly proportional.
4
Q
What are the ways you can speed up rate of reaction?
A
- increase concentration
- increase pressure
- increase temperature
- use a catalyst
5
Q
What is collision frequency?
A
Collision frequency is the amount of successful collisions per second.
6
Q
What is an explosion?
A
An explosion is a very fast chemical reaction that makes and releases large volumes of gases.
7
Q
What does a catalyst do?
A
- it helps reacting particles collide with the correct orientation
- allows collisions between particles with less KE than normal be successful
