C3a - Rate of Reaction 1

You need to be able to:

• Explain the meaning of data given in g/s, g/min, cm3/s or cm3/min with regard to reaction rate

C3b - Rate of Reaction 2

You need to be able to:

• Explain how collision frequency and collision energy effects the rate of reaction
• Explain in terms of particle collisions the changes in rate when pressure, concentration or temperature is altered
