Collision Theory Essay

I film been asked to investigate the effects different component parts such(prenominal)(prenominal) as concentration and temperature have on the rate of chemical chemical reaction The rate of reaction is the loss rate of a reactant or the rate of creation of a product during a chemical reaction and it croupe be measured by dividing oneness by the term offspringn for the reaction be completed.Collision Theory states that an extend in concentration, temperature, surface area and the utilize of a catalyst in a reaction exit either gain the rate of reaction by join on the rate of collision between reactant particles, increase the success rate of collisions between the reactants or both of these reactions, there is in like manner other factor which effects the rate of reaction, only when is only applicable in gasses, that factor being pressure.I have chosen to investigate the effects of Concentration on rate of reaction, as it is the most accurately achievable while still thought-provoking factor to change. Method Equipment- 1x conic flaskful 2x 50ml metre piston chamber 1x 10ml measuring cylinder 1x pipette Sodium Thiosulphate Hydrochloric acid piss Stop time Safety goggle Plain study with a dusky cross on it. Add 10ml of HCL to a cone-shaped flask, by All procedures testament be undertaken with safety goggles on. later assembling all of the equipment I volition pour as close to 10 ml of hydrochloric acid into the 10 ml measuring cylinder, using the pipette to describe the essence as close as reasonably possible, I leave behind when doing this take into account surface tension and thereof fill so the actual amount in the measuring cylinder is at 10ml not a little under as it may appear. I leave behind then gibe (starting with 50ml descending in steps of 5ml to 20ml) sodium thiosulphate to the 50ml measuring cylinder. pursuit this I will add (starting with 0ml move to 30ml in steps of five, in such a manner that the total mickle o f water combined with sodium thiosulphate Is forever and a day at 50ml) water to the second 50ml measuring cylinder. I will then add the two 50ml measuring cylinders contents into the cylinder containing the sodium thiosulphate, leave the cylinder for 10 seconds for the swimmings to mix together (after swirling gently 10 times) before emptying the hydrochloric acid into the conical flask, followed by the mixture of sodium thiosulphate and water.The conical flask will be left wing on top of the opus of paper for the addition of the latter and when the second liquid is poured into the conical flask the stanch clock will be started, I will then proceed to watch the interpret the black cross on the piece of paper bellow the conical flask until the point I can no longer see the black cross, at which instance I will stop the stop clock and record the time taken on a tabularize along with the volumes of liquids used, I will also take the temperature at the time to befuddle sure if there is any major discrepancy caused by the temperature I will know that this is the case and will be able to identify and explain these results.
