Rate of Chemical Reaction between Magnesium and Hydrochloric Acid :: Papers

Rate of Chemical Reaction between Magnesium and Hydrochloric Acid Aim - ====== I plan to investigate the encumbrance of temperature, to see if it increases or decreases the rate of reaction between atomic number 12 and hydrochloric social disease. Prediction - ============= I predict that as the temperature of the hydrochloric acid increases, the quicker the rate of reaction impart be. This is due to the molecules in the hydrochloric acid gaining energy from the heat. Consequently, the molecules have increased kinetic energy, which ordain produce to a greater extent activation energy. The particles will have more prospering collisions resulting in a faster reaction rate.

This is due to the number of successful collisions being far greater when the hydrochloric acid is heated. I predict also that if I did a graph showing the volume of gas against time it would look like the following. IMAGE From the above graph you flush toilet see that when the Time Increases the volume of gas being produced goes up, then it levels off. It levels off because the volume of hydrogen gas being produced is slowing down because all the magnesium and hydrochloric acid is being used up. Fair test ========= In order to keep my experiment as fair as possible I will have to make legitimate I keep the following factors the same - Volume of acid (25cm3) Mass of Magnesium (0.1g) I will make sure the gas syringe is connected correctly and securely to the side arm conical, so no hydrogen gas can escape. I will turn out the syringe at 0 fo r each run. Also I would make sure to put the bung on quickly, to prevent the hydrogen gas escaping.
