Gcse science coursework rates of reactions

Science presenter Jon Chase briefly outlines collision theory and then describes four ways to increase the rate of a reaction. The effect of concentration is demonstrated using an iodine clock Enthalpy 2Page Anjelina Qureshi Mrs Gravell Rates of Reaction Coursework Chemistry Year 11 Enthalpy, in chemistry, is the heat content in a chemical reaction.

The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure. ( May depend on the consistency of your results). For the hydrochloric acid sodium thiosulphate reaction you can plot either (i) reaction time, or (ii) 1time versus a concentration or temperature (1time relative rate of reaction). Rates of reactions coursework (GCSE) Essay by max, High School, 11th grade, A, July 2004 download word file, 2 pages download word file, 2 pages 2.

3 3 votes BUT you can use and extend these 'brain stormed' ideas to most rates of reaction coursework assignments e.

g. The magnesiumzinc acid reaction, you can investigate acid concentration and amount of metal and the zinc reaction is catalysed by copper and other ions in the acid). Jul 02, 2013 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.

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 Reaction Reactions Reactions can only occur when two different particles come together. The theory for the way the reaction occurs is called The Collision Theory. The collision theory states that that the different particles need to 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).

Reaction rates are explained by the collision theory. The collision theory is explained by the rate of reaction. [tags: GCSE Chemistry Coursework Investigation Rates of Reaction Coursework. Introduction. In this piece of science coursework I will be experimenting how the rate of reaction between Sodium thiosulphate and
