Topic 1 Rates of reaction Flashcards
What is the rate of a chemical reaction
How fast the reactants are changed into products
What is one of the slowest
Rusting of iron
What are other slow reactions
Chemical weathering such as acid rain rain damage to limestone buildings
An example of a moderate speed reaction
Magnesium reacting with an acid to produce a gentle stream of bubbles
What are fast reactions
Burning and explosions
Release a lot of gas
How quickly are explosive reactions over
In a fraction of a second
Collision theory
Collision frequency how often they collide
Energy transferred during the collision particles must collide with enough energy for the collision to be successful
What is activation energy
The minimum amount of energy that is needed for particles to break the bonds in the reactants
