Report on the Factors Affecting Rate of Reaction

?Aim: To investigate how soaking up affects the rate of a chemical substance reception between Hydrochloric Acid and Magnesium. Mg(s) + 2HCl (l)MgCl + H?Hypothesis: I trust that the great the parsimoniousness of hydrochloric acid, the faster the reaction provide take place. ?Explanation of Hypothesis: nearly chemical reactions go faster when the concentrations of the reactants are adjoind. This is because in guild for any reaction to happen, those particles must first collide. If the concentration is higher, the chances of black eye are greater because more particles are present consequently the frequency of collision appends and this increases the speed of reaction. Which is why I think that the greater the concentration of Hydrochloric acid used, the faster the reaction give take place. ? implement:Measuring CylinderTest-tube Holder4 Test-tubesDropperStopwatchHydrochloric Acid (2M)Hydrochloric Acid (1M)WaterRulerMagnesium decoration? unsettleds:Independent inconst ant: the concentration of hydrochloric acid used. Dependent Variable: the cadence interpreted for the magnesium typewriter ribbon to dissolve which bequeath change when the concentration of the hydrochloric acid is used. ?Constants:Length of magnesium ribbon used-1 atomic number 49Volume of reactant (hydrochloric acid) used-5 mlRoom temperature and pressure? mathematical operation:1)Cut let out 4 pieces of Magnesium ribbon, each 1 inch in length. 2)Mix 2.5 ml of 1M HCl with an equal volume of water to framing 0.5M HCl. 3)Mix 2.5 ml of 1M HCl with an equal volume of 2M HCl to form 1.5M HCl. 4)Pour the 5 ml of 0.
