What is the collision theory in chemistry?<\/h2>\n

 <\/p>\n

    \n
  1. According to the kinetic theory of matter,<\/strong> particles of matter are in continuous motion<\/strong> and constantly in collision<\/strong> with each other.<\/li>\n
  2. For a reaction to occur, the particles of the reactants (atoms, molecules or ions) must touch each other through collision<\/strong> for bond breaking<\/strong> and bond formation<\/strong> to form the products.<\/li>\n
  3. However, not all collisions will result in a reaction to form the products.<\/li>\n
  4. According to the collision theory, only those collisions which
    \n(a) achieve a minimum amount of energy,<\/strong> called activation energy,<\/strong> and
    \n(b) with the correct orientation,
    \n<\/strong>will result in reaction.
    \nThese types of collisions are known as effective collisions.<\/strong><\/li>\n
  5. For particles that collide with energy less than<\/strong> the activation energy needed for reaction or with the wrong orientation,<\/strong> they simply bounce apart without reacting. <\/strong>These collisions are known as ineffective collisions.<\/strong><\/li>\n
  6. An example to illustrate the collision theory
    \n(a) (i) Hydrogen<\/strong> gas reacts with bromine<\/strong> gas to form hydrogen bromide<\/strong> gas
    \n(ii) The chemical equation for the reaction is H2<\/sub>(g) + Br2<\/sub>(g) \u2192\u00a02HBr(g)
    \n(b) Table illustrates three different situations<\/strong> that may happen during the collisions of hydrogen molecules with bromine molecules.<\/li>\n<\/ol>\n
