Does temperature effect the rate of reaction.

Extracts from this document...


Does temperature effect the rate of reaction. Introduction. I want to find out whether or not temperature speeds up or slows down the rate of reaction. The term "rate of reaction" means the time it takes for reactants to turn into products. Collision theory states the more collisions the faster the rate of reaction will be. If the temperature of a reaction is increased the particles get more energy, they move faster and due to this you get more collisions, and more collisions there are the faster the rate of reaction will be. Increasing the surface area of a reactant makes more exposed area and a higher chance of collisions and this will speed up the rate of reaction. ...read more.


Prediction. I predict that the rate of reaction will increase as the temperature increases. The scientific reasons behind my prediction are the hotter the temperature the more energy particles will be given which makes the reactants move faster also due to this their will be more collisions. I got this information from collision theory. Method. 1. I need to get the equipment and then set it up. 2. Gather the reactants and then measure them out. 3. Collect the sodium thiosulphate and water then place it onto a Bunsen burner flame then heat it to the right temperature in a conical. 4. Put the conical flask on a piece of paper it with a marked cross on it. ...read more.


All of my results followed a pattern because I done the experiment accurately. My results followed this pattern because there was more temperature, more energy so they moved faster which means more collisions and more products. Where made in a shorter space of time. Using my results I can now believe that my prediction was correct. Evaluation. I think my investigation was a success because I got accurately results and they followed a pattern. If I were to do the investigation again I would heat the acid as well as the sodium thiosulphate and water so that the temperature did not fall when cold acid was added. I would also use a pipette for measurement. I could expand my investigation to look at what happens if I lower temperature instead of heating it up. Craig McVeigh Science coursework ...read more.

    I would need to heat the sodium thiosulphate about 2 oC more than I need to because the hydrochloric acid is cold, so when I add it to the heated sodium thiosulphate it will cool it down by a couple of degrees, so if I needed the temperature to be

    � Weight of the whole beaker where the reaction will take place will fall as SO2 gases given off (change will be minute). � The volume of SO2 can be measured using a syringe (very minute volume). � Volume of hydrochloric acid.

    the experiment and a wide range of results can be obtained using temperature. HCl and ethanoic acid are liquids and diluting them with water can make up the correct concentrations of both acids. Magnesium(s) + Hydrochloric acid (l) � Magnesium Chloride (l)

    to wash it with water to avoid the whole piece of magnesium deteriorating and also you have no control over the extensity of corrosion. Therefore I chose to rub it away with sandpaper as you have more control over it and can make the experiment as fair as possible.
