Rate Of Reaction Flashcards
What is the rate of reaction
How fast the reactants are changed into products
How can you find the speed of a reaction
Recording the amount of product formed
Give a description of a fast rate of reaction in a graph
The line will be steep
What must happen in order to react
Particles must collide with enough energy.
What does the rate of recation depend on-2-
- The collision frequency of reacting particles
- the amount of energy transfered during a collision
What are the factors that increase the rate of reaction
- Increasing surface area
- Using a catalyst
- Increasing concentration or pressure
- increasing temperature
When temperature is increased in a reaction what happens
Particles collide more often
What is a catalyst
A substance that speeds up a reaction, without being used up itself
How do catalysts speed up a rate of reaction
Decreasing the activation energy needed for the reaction to occur they do this by providin an alternative reaction pathway
