topic 6 || rate of reaction

the rate and extent of chemical change

what is the collision theory?

what is the collision theory?

in order for particles to react, the particles must:

• collide

• must have at least the minimum activation energy

• must collide the right way round

having all these increases the chance of a successful collision to occur

what are the factors that affect the rate of reaction?

temperature, concentration/pressure, surface area and catalyst

how to calculate the rate of reaction?

quantity of reactants used

how to calculate the rate in a graph?

change in y / change in x

is combustion a fast or slow reaction?

fast

is rusting a fast or slow reaction?

slow
