This is because with heat, the particles of sodiumthiosulphate and hydrochloric acid have more energy. This causes themto move rough more. It works like this for altogether substances, not notwithstandingthose two. Chemical reactions ingest collisions, and if particles are despicable around more quickly they are obviously more likely to collide.It is just like in a crowded street. If the people are move quicklyit is more likely that they go away bump into each former(a) t hen if they aremoving slowly. It is in this way that particles of solutions react.I put together out from preliminary research that the particle theoryexplains that chemical reactions require a collision between theparticles of the reactants, at a accepted speeding and angle. If thisangle or velocity is not achieved, the substances will not reacttogether. I also found out that the factors that affect the rate of areaction are the surface area of the solid reactant (if there is asolid reactant), the concentration of the aqueous reactant(s), thepresence of catalysts and temperature. In this experiment we are onlyinterested in temperature. Where temperature is not high enough to will energy for the particles to move at a high enough speed, theparticles will just not react, or rather, not as many particles willbe able to react together in a certain amount of time.At 0-10C, I yell that the reaction will maintain a very long time toreact. The reason I conjecture this is because alth ough the particles will bemoving around, they will not be moving at a high enough velocity. Forchemical reactions to occur, the particles must be travelling at aparticular speed, and this requires energy. At this temperature I donot think that it will give the particles enough energy to convinceinto movement.Between 11-40C (this includes 3 temperature intervals - 11-20C,21-30C and 31-40C), I predict that the reaction will occur morequickly than that of 0-10C. I think the reaction rate will decreasedramatically at this temperature. I predict this because there is moreheat to provide energy to the particles of the reactants. This energycauses the particles (of sodium thiosulphate and hydrochloric acid) to
