Aim I am going to investigate what factors change the rate of reaction between marble chips and hydrochloric acid. Prediction I predict that the more marble chips there are, the faster the rate of reaction, because there is more marble for the hydrochloric acid to react with, I predict this because in previous experiments when working with the same equipment I found that if you put a lot of marble in the acid, the levels of water in the burette go down very quickly, compared to when you only put a little bit of marble in the acid and the levels of water go down much slower. I also predict that the hotter the temperature of acid, the faster the rate of reaction, because heat often works as a catalyst in experiments with acid. Increasing the temperature of the acid will increase the rate of reaction because particles move faster and collide...
