To investigate how the rate of reaction between sodium thiosulphate and hydrochloric acid is affected by changing the concentration chemistry essay. Steve hacker explains how the concept of reaction rates could be introduced. Go to page chemistry gcse coursework rates of reaction - online open document below is an essay on gcse chemistry investigation coursework from anti essays, your source for research papers, essays, and term paper examples gcse chemistry coursework investigation. My investigation is about the rate of reaction a rate of reaction is defined as how fast or slow a reaction takes place for example, the oxidation of iron under the atmosphere is a slow reaction which can take many years, but the combustion of butane in a fire is a reaction that takes place in fractions of a second. Chemistry coursework this experiment is aimed at investigating how the concentration of reactants affects the rate of reaction: the reaction between hydrochloric acid and magnesium will be used to investigate how different concentrations of the acid affect the rate of reaction the gas produced from the reaction will be.
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 reaction is the speed of a reaction when the solution. A secondary school revision resource for aqa gcse additional science about chemical reactions, energy changes, rates of reaction and reversible reactions. Describes and explains the collision theory for determining how fast reactions take place the individual factors which affect the rate of a reaction ( temperature, concentration, and so on) are discussed on separate pages note: the reason for this lies in some maths beyond the scope of an a'level chemistry course.
My coursework is based on rates of reaction this deals with the time taken for reactants to be changed into products, when the variables are altered and analysed rates of reaction deals with the collision theory, this theory explains how frequently and how hard (sufficient energy) the reacting particles collide with each. 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 corrode active.
The reaction rate or rate of reaction is the speed at which reactants are converted into products for example, the oxidative rusting of iron under earth's atmosphere is a slow reaction that can take many years, but the combustion of cellulose in a fire is a reaction that takes place in fractions of a second for most reactions, the. Chemistry 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 the rate of reaction is the rate of loss of a reactant or the rate of formation of a product the rate is measured by dividing one by the time the reaction took to take place there are.
