How Does Concentration Affect The Rate of A Chemical Reaction? We are going to investigate how the reaction between magnesium and hydrochloric acid is affected by changing the concentration of the acid. To do this I will be changing the concentration of acid slightly while keeping the amount of magnesium the same. I will then record how long it takes for the magnesium to totally react in the range of acid concentrations. Prediction I predict that as the concentration of the acid is decreased, the rate of a chemical reaction on the magnesium is increased. Scientific Reason I believe that this will happen because, as you decrease the concentration of the hydrochloric acid, you are decreasing the amount of acid particles. Because there are fewer particles, there is less chance of them colliding with the magnesium, making the rate of the chemical reaction slower. For a chemical reaction to take place, some bonds in the reactants...
