1
Q
What are the two ways you can measure the rate of a reaction?
A
- how quickly reactants dissapear
- how quickly products appear
2
Q
What are the five main factors affecting the rates of chemical reactions?
A
temp SA presence of a catalyst concentration pressure
3
Q
What is the collision theory?
A
for a reaction to occur, reactant particles must collide with each other with enough energy to overcome the activation energy
4
