The Effect of Temperature on the Rate of Reaction :: GCSE Chemistry Coursework Investigation

The Effect of Temperature on the Rate of ReactionPlanWe must produce a patch of coursework investigating the gaits of reply, and the effect different switchs have on them. The rate of response is the rate of loss of a reactant or the rate of governance ofa product during a chemical reaction. There are tailfin factors whichaffect the rate of a reaction, according to the collision possible action ofreacting touchs temperature, absorption (of solution), pressure(in gases), surface are (of solid reactants), and catalysts.I willing study the effect temperature has on a reaction.AimTo investigate how a change in temperature effects the rate of achemical reaction.The reaction that will be used isSodium Thiosulphate + Hydrochloric Acid -- Na2S2O3(aq)+ 2HCl(aq)Sodium Chloride + Water + south Dioxide + 2NaCl (aq)+ H2O(l)+ SO2(g)+ Sulphur-S (s)PredictionI predict that as the temperature is increased the rate of reactionwill increase. This means that the graph drawn up in my synopsi s willhave positive correlation, and will probably be curving as the increasein rate of reaction will not be exactly the same as the temperature isincreased. This fecal matter be reassert by relating to the collision theory.When the temperature is increased the particles will have more(prenominal) clevernessand thus move faster. Therefore they will collide more oftentimes and withmore energy. Particles with more energy are more likely to vote outthe activating energy barricade to reaction and thus react successfully.If solutions of reacting particles are made more concentrated thereare more particles per social unit volume. Collisions between reactingparticles are therefore more likely to occur. All this can beunderstood better with full understanding of the collision theoryitselfFor a reaction to occur particles have to collide with each other. that a small percent result in a reaction. This is collectible to the energybarrier to overcome. Only particles with enough ener gy to overcome thebarrier will react after colliding. The minimum energy that a particlemust have to overcome the barrier is called the activation energy. Thesize of this activation energy is different for different reactions.If the frequency of collisions is increased the rate of reaction willincrease. However the percent of successful collisions remains thesame. An increase in the frequency of collisions can be achieved byincreasing the temperature, concentration, pressure, and surface area. as well I predict that if the temperature is doubled, then the time takenfor would be more than half because not only would the particles bemoving faster to piddle more collisions, but they would also have moreenergy so there would be more successful collisions
