Introduction/Experiment In this investigation, we study how different factors such as concentration, surface area, temperature, catalysis, solvent, and ionic mediums can affect the rate of a reaction. The reaction examined was as follows: Mg(s)+2HCl(aq) H 2 (g)+MgCl 2 (aq) We must monitor the rate of production of Hydrogen gas and determine the rate law for the reaction. The proposal that we discovered was as follows: Experiment We will place 0.075g of Magnesium in the 125mL flask along with 18mL of 1.0M HCl placing the Magnesium carefully along the side of the tilted flask so that the Magnesium is not introduced into any of the Hydrochloric Acid. A stopper connected to

Unformatted text preview: tubing is attached to the manometer. Then the Magnesium will be tilted so that it is introduced to the Hydrochloric Acid. This is done only after the stopper is securely placed into the flask so that not pressure can escape. A stopwatch on the manometer is started and the pressure inside the apparatus is recorded over ten second intervals. Three trials will be conducted; one for creating the control situation, one changing the surface area of magnesium, and one changing the concentration of the Hydrochloric Acid. Put the trial details here...
