Rate of reaction To investigate the effect, of changing the concentration of a reactant, in a chemical reaction on it rate. The equation used for the experiment was: Sodium + Hydrochloric Sulphur + Sulphur + Sodium + water Thiosulphate acid dioxide chloride Na2S2O3 + 2HCl(aq) S(s) + SO(g) + NaCL(aq) + H2O The Collision Theory can explain reaction rates perfectly. A chemical reaction can only occur between particle when they hit or collide at a minimal amount of energy need for them to react this is called the activation energy. The rates of a reaction depends on how hard and often the reacting particles collide. Basically, particles have to collide in order to react 1) They must also collide hard enough to give a reaction. 2) Pressure can also affect reaction rates between gases, an increase in pressure pushes the molecules closer together making them collide more often, which in turn increases the reaction rate. 3) A presence...
