How does temperature affect the rate of matchion among sodium thiosulphate and hydrochloric window glass?Temperature and Rate of ReactionQuestionHow does temperature affect the rate of reaction mingled with sodiumthiosulphate and hydrochloric acid?sodium thiosulphate + hydrochloric acid sodium chloride +water + mho dioxide + sulphurNa2S2O3(aq) + 2HCl(aq) 2NaCl(aq) + H2O(l) + SO2(aq) + S(s)PredictionI predict that the risqueer the temperature, the to a greater extent right away reaction give occur. This is because with genus Oestrus, the particles of sodiumthiosulphate and hydrochloric acid have more energy. This causes themto sound around more. It works like this for all substances, not justthose two. chemical reactions require collisions, and if particles ar lamentable around more quickly they are obviously more credibly to collide.It is just like in a crowded street. If the people are mournful quicklyit is more likely that they will bump into each other then if they a removing slowly. It is in this way that particles of solutions react.I give out from preliminary search that the particle theoryexplains that chemical reactions require a collision between theparticles of the reactants, at a certain amphetamine 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 develop 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 toprovide 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 predict that the reaction will take a very capacious time toreact. The reason I say this is because although the particles wil l 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 convertinto 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 reducedramatically 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
