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

Rate of Chemical Reaction between Magnesium and Hydrochloric caustic Aim - ====== I plan to investigate the effect of temperature, to see if it increases or decreases the rate of reply between magnesium and hydrochloric stinging. Prediction - ============= I expect that as the temperature of the hydrochloric acid increases, the quicker the rate of reaction result be. This is imputable to the molecules in the hydrochloric acid gaining energy from the heat. Consequently, the molecules have increased kinetic energy, which will produce more activation energy. The particles will have more successful collisions resulting in a faster reaction rate. No heat heat up present Lines of reaction IMAGE Mg turnings Beaker IMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGE Hcl IMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGEIMAGE The above diagram show that when in that r espect is more heat present there are more lines of reaction than if there was less heat. This is due to the number of successful collisions cosmos utmost greater when the hydrochloric acid is heated. I predict also that if I did a graph showing the volume of squander against time it would look desire the following. IMAGE From the above graph you can see that when the Time Increases the volume of muff being produced goes up, then it levels off. It levels off because the volume of hydrogen blow being produced is slowing down because all the magnesium and hydrochloric acid is being apply up. Fair test ========= In order to keep my experiment as fair as possible I will have to coiffe sure I keep the following factors the same - Volume of acid (25cm3) Mass of Magnesium (0.1g) I will drag sure the gas syringe is connected correctly and securely to the side arm conical, so no hydrogen gas can escape. I will leave the syringe at 0 for each ru n. Also I would make sure to put the bung on quickly, to prevent the hydrogen gas escaping.
