Collision Theory Essay

I have been asked to check out the do different factors such as concentration and temperature have on the rate of reaction The rate of reaction is the loss rate of a reactant or the rate of creation of a product during a chemical substance reaction and it can be measured by dividing one by the time taken for the reaction be completed.Collision Theory states that an change magnitude in concentration, temperature, surface area and the use of a catalyst in a reaction depart either increase the rate of reaction by increasing the rate of collision between reactant particles, increase the triumph rate of collisions between the reactants or both of these reactions, there is also another(prenominal) factor which effects the rate of reaction, but 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 challenging factor to change. Method Equipment- 1x con e-shaped flaskful 2x 50ml measuring piston chamber 1x 10ml measuring cylinder 1x pipette Sodium Thiosulphate Hydrochloric biting Water Stop time Safety goggles Plain newspaper with a black cross on it. Add 10ml of HCL to a conical flask, by All procedures will be undertaken with safety goggles on. later assembling all of the equipment I will pour as smashed to 10 ml of hydrochloric erosive into the 10 ml measuring cylinder, utilize the pipette to get the amount as close as passably possible, I will when doing this take into account surface tension and thusly fill so the actual amount in the measuring cylinder is at 10ml not a little under as it whitethorn appear. I will then add (starting with 50ml descending in move of 5ml to 20ml) sodium thiosulphate to the 50ml measuring cylinder.Following this I will add (starting with 0ml cost increase to 30ml in steps of five, in such a manner that the substance volume of water system combined with sodium thiosulphate Is always at 50 ml) 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 liquids 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 on top of the piece of paper for the addendum of the latter and when the second liquid is poured into the conical flask the persist clock will be started, I will then proceed to look on the view the black cross on the piece of paper yaup the conical flask until the point I can no endless see the black cross, at which instance I will stop the stop clock and record the time taken on a table along with the volumes of liquids used, I will also take the temperature at the time to make sure if there is any major variety caused by the temperature I will know that this is the case and will be able to identify and explain these results.
