Investigating the rate of diffusion of ammonia :: GCSE Chemistry Coursework Investigation

Investigating the rate of scattering of ammoniaInvestigating the rate of diffusion of hydrochloric acid in agar-agarPlanningYou can change antithetical things you do to an experiment same(p) the measure of acid, temperature, size of the agar or tightfistedness of theacid.We can ginmill/observe on how long it takes to diffuse or the bar flaccid each minute.My partner and I be going to predict and stair the rough time itwill take to diffuse at different temperatures.The factors that may affect the readings of our results atomic number 18 if thetemperature of the room may reduce the temperature of our peeing bathsor if the windows open.There may be a human geological fault were the person which is timing may notget it exactly refine or you may not be able to measure the amount ofacid correctly.We are going to do the experiment trinity generation and work out the meantime by adding the times unneurotic then dividing by however manyreadings youve added. You have to do them three times just in casethe temperature varied. But you should get them more or less around a time.To sacrifice it a fair test you must only change one factor. The factorsthat we are keeping the same are the amount of acid you test it in,the size of the agar cube and the container you do the experiment in.You have to keep the container the same because with a wider containerwill make it depend like there is only a small amount of acid were as a change state tube would make it seem like there is quite a lot. The factorthat we are changing is the temperature of the water bath, which wewill keep it in for however long it takes to diffuse.I predict that the higher the temperature of Hydrochloric acid , thefaster it will diffuse.Found my discipline at www.britannica.comWhat are the factors that affect chemical reaction rate?solvent foundation talent, temperature, method, concentrations,particle size, and surface areaReactive impact chemical reaction takes place only when two rea ctantscollide under the adept conditions. The higher the temperature themore reactants with kinetic energy above the activation energyEffect of temperatureincreasing temperature to overcome theactivation energy barrier and to development entropy (a measure of theconfusion of the molecules in a substance)Effect of concentrationincreasing colliding frequencyWhen you heat a solution up the partials press forward up and in this casemove the partials in the agar so much it forms a chemical reaction.The apparatuses we are going to use are 1 cm agar, boiling tubes,water baths at different temperatures, ice, boiling tube rack,
