Rates of reaction Flashcards
What is the rate of reaction?
How fast the reactants are changed into products
Name some slow reactions
Weathering of rock
Rusting of iron
Name medium fast reaction
Magnesium reacting with an acid
How can you calculate the rate of reaction using a graph?
Plot amount of product formed against the time or amounts of reactant used up
What does the gradient of the line tell you?
Steeper = faster reaction
Why do rate of reaction lines eventually flatten out?>
The reactants are used up
What must happen in order for particles to react?
They must collide with enough energy
What is the name of the theory used to explain reaction rates?
Collision theory
What is collision theory?
The more collisions there are the faster the reaction is.
What is the activation energy?
The minimum amount of energy required to react
What is deemed a successful collision?
A successful collision that ends in the particles reacting to form products
