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. The rate of Chemistry Coursework Rates of Reaction Investigation Introduction In this investigation I am going to be investigating the reaction between marble chips and hydrochloric acid, and to see what differences in the rate of this reaction arise when different concentrations of acid are used.
Sep 18, 2018 The gas products move towards the measuring cylinder cO2 The rate of reaction depends on how hard and how often the reacting particles collide with each other.
I think most universities let undergraduates work in the lab, holding a chemistry coursework rate of reaction conclusion tube. Investigating the rate of a reaction 1. Preliminary work Analysis and Evaluation This must be an individual activity. As with planning, enabling commentsquestions are allowed, but do GCSE Chemistry Coursework: Investigating the rate of a reaction Your task is to plan, and carry out, an experiment to discover how to change the rate the Investigating how the concentration of sodiumthiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment.
In addition I am also checking how different variables affect my experiment and also how I can make my test more precise, reliable and accurate. Strategy According to my results, as the concentration of STS Analysis The results show that the rate of reaction decreases when the sodium thiosulphate is less concentrated. From the graph we can see that as the concentration decreases, the time taken increases. The rate of reaction between sodium thiosulphate and hydrochloric acid Candidate name: Yeo Jin Kim SCIENCE COURSEWORK I am going to investigate how the rate of the reaction between sodium The solid sulphur (S(s)) formed in this reaction makes the colourless solution go cloudy.
