  1. Question 1Skills & concepts

    Knowing reaction rates is important for applications such as creating medicines, reducing pollution and

    • aprocessing food
    • bpainting houses
    • cwriting music
    • dmeasuring land
  2. Question 2Skills & concepts

    Rate can be expressed using change in concentration, moles or

    • amass
    • bcolour
    • ccharge
    • dpressure only
  3. Question 3Strategic thinking

    The initial rate is often the fastest rate because at t = 0 the

    • areactant concentration is highest
    • bproducts are highest
    • ccatalyst is absent
    • dtemperature is lowest
  4. Question 4Skills & concepts

    The average rate of reaction is calculated by dividing the change in concentration by the

    • atime elapsed
    • bmass of catalyst
    • cvolume of flask
    • dnumber of atoms
  5. Question 5Skills & concepts

    Measuring how fast a reactant disappears is one way of finding the

    • arate of reaction
    • benthalpy change
    • cmolar mass
    • doxidation number
