3: Reaction rate and temperatures Flashcards
1
Q
What happens to the rate of reaction when the temperature is decreased?
A
As the temperature decreases, so does the rate of reaction
2
Q
In terms of particles, what happens to the rate of reaction when the temperature is increased?
A
Particles have more energy at higher temperatures, so they will move faster and the collisions will be more frequent. Therefore the reaction will happen faster.
3
Q
What is an unsuccessful collision between reactant particles?
A
At low temperatures the amount of energy transferred in a collision may not be enough to cause a reaction.
4
Q
What does the rate of reaction depend on?
A
> amount of energy transferred during collisions
>frequency of collisions
