Rate of Reaction - Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen, (Mg +2HCl → MgCl2 + H2) Free Essay, Term Paper and Book Report
Aim:
The aim of this investigation is to find out whether the surface area of the metal has an effect on the rate of reaction in the chemical reaction Magnesium + Hydrochloric acid → Magnesium chloride + Hydrogen, (Mg +2HCl → MgCl2 + H2).
Hypothesis
I think that the more surface area there is, the faster the reaction will be. For example, I think that when the surface area of the magnesium is 4 strip of 0.5cm that the rate of reaction will be very fast and when the surface area is just one single strip of magnesium of 2cm long, the rate of reaction will be much slower. My reason for saying this is because as the surface area increases, there are more magnesium particles that need to react with the Hydrochloric acid particles. If there are more particles there is a much higher chance of collision between the magnesium particles and the hydrochloric acid particles, and therefore the reaction will occur a lot faster. The metal is spread out so more atoms are exposed to the acid particles.
Variables

Dear Free Essays:
Thanks for helping me with my term paper!
With so many essays and term papers on your service, I got a few ideas from mixing and matching and managed to write a great paper in 1/10 the time. My teacher thought so too because I got an A grade. Thank you so much!
