Investigating a factor that affects the rate of an acid/ metal reaction Problem In this essay I am going to investigate the effect of changing the temperature on the reaction between Magnesium and Sulfuric acid. Hypothesis I expect that as the temperature increases the reaction will go faster because the determining factor of the speed of a chemical reaction are the collisions between molecules. The more frequently they collide, the greater the likelihood that a reaction will take place. By increasing the temperature it increases the number of collisions and also increases the energy of the collisions Variables Our independent variable was the temperature of Sulfuric Acid, which we increased by 10C in each reaction. Our dependent variables was the time it took for the Magnesium to dissolve. Our Controled Variables were : -Same amount of sulfuric (5ml) acid and magnesium (0,01g) in each reaction. -Same types of reaction vessels (beaker ,test tube) -Take...
