    Cards (6)

    • what is cracking
      • the breaking down of large hydrocarbons
      • into smaller more useful hydrocarbons
    • why is there a large demand for smaller hydrocarbons
      • they're more useful as fuels
      • than large hydrocarbons
      • because they're more flammable
    • Describe two reasons why cracking is useful
      • it can produce smaller alkanes that are in high demand as fuels
      • it can produce alkenes that are used as feedstock e.g making polymers
    • what is steam cracking
      • involves mixing a hydrocarbon with steam
      • and heating the mixture
    • what is catalytic cracking
      • involves heating a hydrocarbon
      • in the presence of a catalyst
    • what two types of hydrocarbons are produced by cracking
      • alkanes
      • alkenes
