AS2.6 Chemical Reactivity (External)
This externally assessed standard is worth 5 credits and is essential for
understanding at Level 3.
You will cover a large amount of content and the teaching  component will take
approximately 10 weeks of class time.

The following is a comprehensive list of all the key areas that you must cover for AS2.6.

what you need to know!

Chemical reactivity is limited to rates of reaction and equilibrium principles.

Rates of reaction involve:

  • factors affecting rates of reaction – restricted to changes in concentration, temperature, surface area, and the presence of a catalyst
  • using collision theory to explain the factors (includes activation energy). 

Equilibrium principles are limited to:

  • the dynamic nature of equilibrium
  • the effect of changes in temperature, concentration, pressure, or addition of a catalyst on equilibrium systems
  • the significance of the equilibrium constant (Kc) for homogeneous systems.  This may involve calculations
  • the nature of acids and bases in terms of proton transfer
  • properties of aqueous solutions of strong and weak acids and bases including ionic species.  The properties are restricted to conductivity, rate of reaction, and pH
  • calculations involving Kw and pH (restricted to strong acids and bases).
