Rates Of Reaction (UNFINISHED) Flashcards
1
Q
What is the definition of ‘rate of reaction’
A
How fast the reactants are going to change into products
2
Q
How do you work out rate or reaction
A
Rate = Amount of reactant used
———————————
Time
Or amount of product formed
————————————
Time
3
Q
What are the factors that affect rate of reaction
A
1: Temperature
2: Concentration/pressure
3: Surface area
4: Presence or absence of a catalyst

Q
What is the collision theory
A
For a reaction to happen particles must collide
The more frequent the collisions are the faster the reaction
However for a reaction to happen particles must have the minimum amount of energy required to collide
This is called activation energy
