Collision Theory Flashcards
What does the rate of chemical reactions depend on?
How frequent successful collision happen.
And how much activation energy is required to start the reaction.
What do more collisions mean?
The higher the rate of reaction as more particles hit each other meaning more energy given off and more energy released.
Why does temperature increase rate of reaction?
As particles move fast which mean more chance of collisions therefore more successful collision will lead to enough energy to start the reaction
How does concentration increase rate of reaction?
As if it’s more concentrated the particles are closer together meaning that the particles have a higher chance of hitting each other . This means that more successful collisions will happen meaning that rate of reaction will increase.
How does surface area affect rate of reaction / why does it increase it?
As the greater surface area means that there is more area for particles to potentially hit meaning that there is a greater chance of successful collisions , this means that an increased rate of reaction .
It works better with a higher surface area to volume ratio.
