Investigating how varying the concentration of hydrochloric acid affects the rate its reaction in a given time. Prediction: The collision theory worked on the idea that particles "crash" into the substance that they come in contact with therefore causing a reaction. The surface area has a big affect on this. Whatever I choose to be the size of my chips the particles will only collide with what is on the outside of the marble chips. If I choose big marble chips then there would still be lots of marble not exposed to the acid particles therefore not being able to react. Choosing small marble chips will give me a faster reading because there will be more marble to react. When you increase the concentration of a substance in a certain space, the number of particles in that substance increases. So by adding acid of a higher concentration, you are effectively cramming more...
