Does The Temperature Of Hydrochloric Acid Affect The Rate Of The Chemical Reaction Between Hydrolic Acid And Magnesium? Analysis Temperature of Time taken for Seconds hydrochloric acid 0c magnesium to react 14 141 20 80 27 73 39 55 50 52 60 51 Hydrochloric acid + magnesium magnesium chloride + hydrogen 2 Hcl MG MGCL2 H2 From my results I can conclude that the hotter the hydrochloric acid the quicker the reaction time between the acid and magnesium. The results show certain patterns and trends, for example the test where the acid was at 14 C the magnesium took 141 seconds to react and 27 C test took 73 seconds to react. This shows roughly that if you double the temperature then the reaction time will half. The reason that when the hydrochloric acid was at 14 C the reaction time for all the magnesium to react was 141 seconds was because the molecules of the acid and magnesium didn’t have a lot of kinetic energy, so there was not much movement therefore there were not many successful collisions. Successful collisions are when the molecules contain enough kinetic energy to collide forcefully enough to break the bonds between the hydrogen and the chloride particles this needs to take place for any reaction to happen. If there is not a sufficient amount of kinetic energy, the particles just bounce off of each other causing no reaction. On the other hand the reason when the
