Investigating the rate of diffusion of ammoniaInvestigating the rate of diffusion of hydrochloric acid in nutrient agarPlanningYou can change different things you do to an experiment corresponding theamount of acid, temperature, size of the agar or concentration of theacid.We can cadency/observe on how long it takes to diffuse or the amountdiffused each minute.My partner and I are going to predict and measure the knockabout fourth dimension itwill take to diffuse at different temperatures.The factors that may affect the readings of our results are if thetemperature of the room may reduce the temperature of our water bathsor if the windows open. on that point may be a human error were the person which is timing may notget it exactly correct or you may not be able to measure the amount ofacid correctly.We are going to do the experiment three times and work out the meantime by adding the times together then dividing by however manyreadings youve added. You have to do them three time s just in casethe temperature varied. but you should get them roughly around a time.To throw it a fair test you must only change one factor. The factorsthat we are keeping the aforesaid(prenominal) 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 seem 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 high the temperature of Hydrochloric acid , thefaster it will diffuse.Found my information at www.britannica.comWhat are the factors that affect chemical reaction rate?Answer foundation heftiness, temperature, method, concentrations,particle size, and move up areaReactive impact Chemical reaction takes place only when two reactants collide under the right conditions. The higher the temperature themore reactants with kinetic energy above the activation energyEffect of temperatureincreasing temperature to overcome theactivation energy barrier and to increase entropy (a measure of theconfusion of the molecules in a substance)Effect of concentrationincreasing colliding frequencyWhen you heat a solution up the partials speed 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,
