Chemical are produced on an industrial scale. It is really important to
control the rate of reactions. Discuss factors which can affect the rate of
reaction. Consider the collision theory in your answer.
6 marks
Key words
Concentration
Surface Area
Temperature
Catalysts
Collision Theory
Particles
Hints
List the factors
that affect the
rate of reaction
Explain how each
factor can change
the rate of
reaction
Explain what
collision theory is
and link this to
the different
factors
Explain why not
all collisions of
particles cause
a reaction
