Rates of reaction Flashcards
1
Q
What is the rate of a chemical reaction?
A
How fast the reactants are turned into products
2
Q
Example of a slow reaction
A
Rusting
3
Q
Example of a middle speed reaction
A
Apple core turning brown
4
Q
Example of a fast reaction
A
Burning/explosions
5
Q
Particles must collide with enough energy in order to react
A
1) The collision frequency of reacting particles (how often they collide). The more collisions there are the faster the reaction is.
2) The energy transfer during a collision. Particles have to collide with enough energy for collisions to be successful.
6
Q
Activation energy
A
The minimum amount of energy required to start the reaction
