* Investigating rates of reaction between hydrochloric acid and sodium thiosulphate and how heat/ temperature of the solution affects this rate. * Background Knowledge: Reaction rates are explained by collision theory, this is because it states that the rate of reaction depends on how frequently and strong the reacting particles collide, in other words the particles have to collide to react and collide with strength. There are four ways that help speed up the rate of reaction using collision theory. These are temperature, concentration, size of particles (surface area) and catalysts. Temperature increases the rate of reaction because when the temperature increases the particles move quicker, this means the particles will have more collisions. Concentration increases the number of collisions as well. If the solution is more concentrated there are more particles of reactant between water molecules, which makes collisions between the other particles more likely. The size of solid particles creates a...
