The Effect of Concentration and the Rate of Reaction between Sodium Thiosulphate and Dilute Hydrochloric Acid Introduction I am going to be investigating the effect of concentration and rate of reaction between sodium thiosulphate (NA) and dilute hydrochloric acid (HCI). Rate is a measure of how fast or slow something happens e.g. a plane flew 2000km in 1 hour therefore; it flew at a rate of 2000km/hr. There are five main factors that affect the rate of reaction:> Catalyst> Concentration> Temperature> Surface Area> Pressure/Light Catalyst: When a catalyst is added to a reaction it changes the rate and makes the reaction happen faster most of the time. When a catalyst is added it breaks the bonds in the reactant and makes new bonds, as the particles are now smaller there is less resistance and therefore the particles move faster or have a bigger surface area exposed so the acid can make contact and react....
