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 …showed first 75 words of 975 total…

…showed last 75 words of 975 total…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.
