Rates of reaction Flashcards
1
Q
Rate of reaction
A
How fast the reactants are turned to products
2
Q
Example of slow reaction
A
Rusting
3
Q
Example of a fast reaction
A
Explosion
4
Q
How to find RoR
A
- Measure how much reactant is used
up over time - Measure how much product is formed
over time
5
Q
Properties of the graph
A
- The steeper the line. the faster the
reaction - the line gets less steep over time as
the reactants are used up
6
Q
Collision theory
A
The collision theory states that particles must collide with sufficient energy (activation energy) in order to react.
7
Q
How to calculate RoR
A
amount of reactant used / time
8
Q

A
salt + carbon dioxide + water
