Science - C3 - Rates of Reaction

HideShow resource information
What is rate of reaction?
How much product is made in a fixed time.
1 of 6
The higher the temperature...
The more successful the collisions between particles.
2 of 6
The higher the concentration...
The higher the collision frequency of reacting particles.
3 of 6
What is a catalyst?
They speed up the rate of reaction but remain unchanged at the end.
4 of 6
Fine powders are more COMBUSTIBLE...
as they have a greater surface area exposed.
5 of 6
Increasing pressure increases rate of reaction
as there are higher numbers of successful collisions.
