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
