The speed of chemical reaction between Calcium carbonate and Hydrochloric acid

In my assessment I am going to say how I think the concentration of acid effects the speed of a reaction. I will do this by using:
. Collision theory
. Kinetic theory
. Diagrams
. Graphs
In this diagram the particles In this diagram the particles
have a low concentration have a higher concentration
of acid. Also there are of acid. There is the same
few marble chips for amount of marble chips, but
the particles…
