With over 20 years of trust in our products, the international boating community knows that when it comes to a mount for electronics, they choose ‘a scanstrut. The temperature of the reaction mixture the concentration of the sodium thiosulphate the concentration of hydrochloric acid changing the pressure in this particular investigation i am going to find out how heat affects the rate of reaction in the reaction of sodium thiosulphate with hydrochloric acid. Catalyst adding a catalyst will speed up a reaction by decreasing the energy needed to break the bonds a catalyst is not chemically consumed by the reaction so does not have an effect on the final products pressure pressure results in there being more particles of each reagent in a smaller area, resulting in more reactions. The units for rate are usually cm 3 s-1 or cm 3 min-1 two ways to measure the volume of a gas produced in a reaction graphs the rate of reaction can be analysed by plotting a graph of mass or volume of product formed against time the graph shows this for two reactions the steeper the line, the greater the rate of reaction. ( may depend on the consistency of your results) for the hydrochloric acid - sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1/time versus a concentration or temperature (1/time = relative rate of reaction.
Rates of reactions part of description classroom ideas description science presenter jon chase briefly outlines collision theory and then describes four ways to increase the rate of a. A grade gcse chemistry coursework, rates of reaction, decomposition of sodium thiosulphate, introduction, method, safety, results, discussion sodium thiosulphate decomposition for gcse, grade a easy. Chemistry rate of reaction coursework – gcse science – marked by plan i am going to produce a piece of coursework investigating the rate of reaction, selecting a variable to see how this affects the rate.
Disappearing cross (aka rate of reaction) prediction i predict that the higher the temperature used in the experiment the faster the solution will become cloudy and cover up the cross i think the speed of the reaction will considerably change from the temperatures 200c to 600c (the rate of reaction will increase.
- rates of reaction coursework introduction in this piece of science coursework i will be experimenting how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by the concentration of sodium thiosulphate.
Anjelina qureshi mrs gravell rates of reaction coursework chemistry year 11 rates of reaction introduction a chemical reaction occurs when things change from reactants into products these reactions only happen if the reacting molecules collide properly.

Chemistry science coursework investigating the effect of changing concentration on the rate of a reaction introduction magnesium is a highly reactive metal, in the reactivity series what i will be investigating in this experiment is to try and find out whether or not there is any correlation between the concentration of the hydrochloric acid and the rate of reaction.
Chemistry rate of reaction coursework – gcse science – marked by plan i am going to produce a piece of coursework investigating the rate of reaction, selecting a variable to see how this affects the rate rates of reactions chemistry coursework 380446 ocpsoft. Doc brown's chemistry ks4 science gcse/igcse revision notes a brainstorm on rates of reaction for chemistry coursework investigations-projects this page should help with rates of reaction coursework projects or assignments investigations.
Rates of reaction gcse coursework chemistry 2004 aim in the experiment we use hydrochloric acid which reacts with the magnesium to form magnesium chloride the hydrogen ions give hydrochloric acid its acidic properties, so that all solutions of hydrogen chloride and water have a sour taste.
