Collision Theory Flashcards
What does higher temperatures do to the number of collisions:
Increases collisions
When the temperature is increased what does it mean for the particles:
The particles all move quicker
What does it mean when the temperature is increased and the particles move quicker:
If they’re moving quicker, they’re going to have more frequent collisions
What does higher concentration do to the number of collisions:
Increases collisions
What does it mean if a solution is made more concentrated:
Means there are more particles of reactant knocking about between the water molecules.
What does a higher concentration make the collisions between the particles:
More likely
What does a larger surface do to the number of collisions:
Increases collisions
More collisions does what to the reaction:
Increases the rate of reaction
Faster collisions are only caused by:
Increasing the temperature
When do reactions only happen:
When particles collide with enough energy
Why do reactions only happen if the particles collide with enough energy:
Because there’s a minimum energy needed to break the initial bonds
What happens to make the reaction happen at a higher temperature:
At a higher temperature there will be more particles colliding with enough energy to make the reaction happen.
What do catalysts do to the number of collisions:
Increase the number of successful collisions
How does a solid catalyst work:
By giving the reacting particles a surface area to stick to they increase number of successful collisions by lowering energy particles needed to start reacting with each other
