SPM Chemistry Form 5 Definition List:

  1. Effective collision (Collision theory) – collision that results in a chemical reaction where the particles collide with the correct orientation and are able to achieve the activation energy.
  2. Homologous series – organic compounds (families) with similar formulae and properties.
  3. Catalyst – a chemical that alter the rate of reaction.
  4. Positive catalystincreases the rate of reaction & lower the activation energy.
  5. Negative catalystdecreases the rate of reaction & higher the activation energy
  6. Organic compounds – carbon-containing compound. Carbon atoms form covalent bonds.
  7. Inorganic compounds – compounds from non-living things which do not contain the element carbon.
  8. Saturated hydrocarbons – hydrocarbons containing only single bonds between all carbon atoms.
  9. Unsaturated hydrocarbons – hydrocarbons containing at least one carbon-carbon double or triple bond.
  10. Esterification – esters are produced
  11. Vulcanisation – process which makes the natural rubber harder and increases its elasticity by adding sulphur.
  12. Redox reaction – chemical reactions involving oxidation and reduction occurring simultaneously.
  13. Flavouring – improve the taste or smell of food and restore taste loss due to food processing.
  14. Stabilisers – help to mix two liquids that usually do not mix together so that they form an emulsion.
  15. Thickeners – substances that thicken food and give the food a firm, smooth and uniform texture.
  16. Precipitation – the heat change when one mole of a precipitate is formed from their ions in aqueous solution.
  17. Displacement – the heat change when one mole of a metal is displaced from its salt solution by a more electropositive metal.
  18. Neutralisation – the heat change when one mole of water is formed from the reaction between an acid and an alkali.
  19. Combustion – the heat change when one mole of a substance is completely burnt in oxygen under standard conditions.

So there you go!!! 19 of the most common definitions for SPM Form 5 Chemistry.
