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 to collide …

…be a particles to collide with each slow reaction. other. This explains why there is a faster reaction. Comparing the graphs: The line that shows the 2m acid is steeper than the line that shows the 0.5m acid. This is because the reaction was faster and it gave out a higher volume of gas. Both the 1.5 and the 1m acids are steeper than the 0.5m acid. This maybe my results or it could be right.
