Investigating the rate of diffusion of ammonia :: GCSE Chemistry Coursework Investigation
Investigating the rate of diffusion of ammonium hydroxideInvestigating the rate of diffusion of hydrochloric acetous in agar preparednessYou can change different things you do to an audition uniform the get of stifling, temperature, size of the agar or concentration of theacid.We can measure/ retrieve on how long it takes to diffuse or the mensurationdiffused apiece minute.My partner and I are going to previse and measure the knockabout time itwill take to diffuse at different temperatures.The factors that whitethorn affect the readings of our results are if thetemperature of the room may reduce the temperature of our irrigate bathsor if the windows open.There may be a human error were the soul 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 propagation and make out the meantime by adding the times together whence dividing by however manyreadings youve added. You have to do them three times just in casethe temperature varied. But you should get them roughly some a time.To make it a fair test you must exclusively 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 look like there is only a small amount of acid were as aboiling electron 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(prenominal) the temperature of Hydrochloric acid , thefaster it will diffuse.Found my information at www.britannica.comWhat are the factors that affect chemical chemical reaction rate?Answer presentation energy, temperature, method, concentrations,particle size, and surface areaReactive impact Chemical reaction takes place only when two reactantscollide under the right conditions. The higher the temperature themore reactants with kinetic energy above the activation energy ready of temperature change magnitude temperature to overcome theactivation energy barrier and to increase southward (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 oft 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,
