How does increasing temperature affect the rate of reaction?
By increasing the temperature, the particles are vibrating more and move around faster, increasing the rate of collision so increasing rate of reaction.

What is Collision Theory and how does it affect rate of reaction?
For a reaction to happen, reactant particles must collide with eachother. The minumum energy required in order to have sucessful collision is call activation energy. (Collisions must have energy)

How does concentration affect rate of reaction?
The higher the concentration, the more (e.g) hcl molecules wich means more succesful collisions which means increased rate of reaction
3 of 6
How does surface area affect rate of reaction?
The more surface area means more particles exposed to reactants, so more collisions and increased rate of reaction.

The two ways to measure a rate of reaction are:
1.Measure the rate at which a reactant is used up Measure the rate at which a product is formed

How does the graph affect reactions?
The steeper the line, the greater the rate of reaction.
