Factors affecting RoR Flashcards
1
Q
What are the 3 factors affecting the RoR?
A
Surface area, temperature, concentration
2
Q
Relationship with collisions
A
directly proportional
3
Q
Temperature
A
As temp increases particles move faster and collide more with more energy.
4
Q
Concentration
A
As concentration increases, their are more particles meaning there are more collisions
5
Q
Surface area
A
As surface area increases, more particles of the solid are exposed to collisions.
6
Q
How to calculate RoR
A
amount of reactant used / time
