Gcse chemistry coursework rates of reaction concentration

An experiment suitable for gcse science investigating the effect of concentration and temperature on the rate of reaction. The effect of concentration on reaction rate essay - the effect of concentration on reaction rate introduction: in this experiment, we utilized the ability for the iodide ion to become oxidized by the persulphate ion our general reaction can be described as: (nh4)2s2o8 + 2ki ã i2 + (nh4)2so4 + k2so4 (1a) however, we. Does the amount/concentration of a catalyst present in a reaction affect the rate at which the reaction proceeds 0 reply sorry if you already knew that (as it's just gcse) 1 reply in the last part you had to decide on how you could change the experiment to show something and then do it i got that. 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. An experiment investigating how the concentrations of the reactants affect the rate of reaction aim to find out how the concentrations of the reactants affect the rate of reaction scientific knowledge reactions can go at all sorts of different rates eg a slow reaction would be the rusting of iron and a really fast reaction is an. Data generated in rate experiments is typically reliable enough to analyse mathematically and cross-curricular links to gcse mathematics, in particular the gradient at the experiment can be used to show how the rate of reaction is affected by surface area or concentration and is available from the nuffield foundation.

This is an experiment from the practical chemistry project, developed by the nuffield foundation and the royal society of chemistry nuffield foundation the- rate-of-reaction-of-m. A secondary school revision resource for ocr gcse science about rocks, metals, collision theory and rates of reaction. Vary the concentrations of reactants and measure the time it takes for product to appear this video is part of the flinn scientific best practices for teaching chemistry video series, a collection of over 125 hours of free professional development training for chemistry teachers - http://elearningflinnscicom. Affect the speed of the reaction if i was to use a bunsen burner it might blow the flame out and the test will have to be repeated • the concentration of the reactants will have an affect because if it isn't mixed or measured accurately the reactions will happen at a different rate each experiment will be tested in the same area.

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 there are five factors that affect the rate of reaction: temperature concentration (of solution) pressure (in gases) surface area (of solid reactants) catalysts i have decided to. A grade gcse chemistry coursework, rates of reaction, decomposition of sodium thiosulphate, introduction, method, safety, results, discussion sodium i have done preliminary work to work out the right amounts/concentrations etc to use and also to decide the best range results below is a table to show.

  • During your isa we will give you a description of the context of the experiment i want to measure speed of reaction at different concentrations same size of marble chips so this does not affect the rate of the reaction tyler will use the same temperature by using a water bath as higher temperature would increase the rate.
  • Factors that affect the rate of reaction of calcium carbonate with acid controlled chemistry a and to the guide for controlled assessment for gcse twenty first century science task setting is we carried out a preliminary experiment this was to test how the concentration of an acid affected the.
  • The effect of concentration on the rate of reaction between magnesium [mg] and hydrochloric acid [hcl] by mohammed thamid azad candidate number- 5021 when you are doing an experiment in order to make a product you should know how long the reaction takes to complete, before the product is produced.

Trial run 1 – how concentration of sodium thiosulphate affects rate in this experiment we did a trial run to familiarise ourselves with the experiment and the equipment it also helps us what kind of patterns we expect to get the concentration of sodium thiosulphate was changed by adding water the solution was tested. Rhubarb rhubarb rhubarb this investigation looks at rates of reaction by using the reaction between oxalic acid in the rhubarb and potassium manganate vii as described, the investigation looks at concentration and surface area but temperature would be an easy addition rhubarb rhubarb - experiment guide. Introductionconcentration and surface area of reactant, temperature, and catalyst are the factors that affect the rate ofa reaction in this experiment the reaction between hydrochloric acid solution and magnesium ribbon isused to investigate the effect of reactant concentration on the rate of reaction.
