  • Chemical reactions can occur at vastly different rates
  • The reactivity of chemicals is a significant factor in how fast chemical reactions proceed
  • There are many variables that can be manipulated in order to speed up or slow down chemical reactions
  • Chemical reactions may also be reversible
  • The effect of different variables needs to be established in order to identify how to maximise the yield of desired product
  • Understanding energy changes that accompany chemical reactions is important for this process
  • In industry, chemists and chemical engineers determine the effect of different variables on
    1. Reaction rate
    2. Yield of product
  • Whilst there may be compromises to be made, they carry out optimisation processes to ensure that enough product is produced within a sufficient time, and in an energy-efficient way
