Rates Of Reaction draw a bead on To find out the effect of acid concentration in abbreviate hydrochloric acid and milligram laurel wreath, and how much hydrogen gas is given off. expectancy I predict that as the concentration of the hydrochloric acid increases the time interpreted for magnesium ribbon to ignore leave decrease. Apparatus Saturated ladder tube Rubber bung Bowl water Magnesium ribbon Concentrated hydrochloric acid Plastic tube Stopwatch Conical flaskful Measuring cylinder The concentration of the acid is going to be my tho variable. It will vary the time keepn for the magnesium ribbon to dissolve into the acid. Other things that I will be using argon non going to be varied these are volume of hydrochloric acid and magnesium ribbon. The magnesium ribbon dissolves into the hydrochloric acid because then it collides with the particles inside the hydrochloric acid. Activation dexterity is minimum amount of energy r equired for a reaction to take place. For each of the concentrations I use the activation energy will be different. If the activation energy is high then only a humiliated amount of particles will have enough energy to react yet if the activation energy is low then a lot much particles can react. The reaction will also be exothermic because it will be giving off heat and hydrogen gas. A wobble in concentration is a change in the number of particles in a volume. If we increase the volume the particles will collide much because they are crowded. Factors The factors that could affect the rate of reaction are as follows Concentration of window glass This could affect the rate of reaction because the higher that concentration of the acid the more particles there are so there is more collision per second. Temperature If the start temperature of the acid is different each time then the speed at which the atoms will collide will increase or decreas e depending on what the temperature is.
