WHAT FACTORS AFFECT THE RATE OF A REACTION? AIM- To investigate one factor that will affect the rate of reaction between magnesium and hydrochloric acid. Factors that would affect the rate of this reaction are: 1) CONCENTRATION- if the hydrochloric acid is made more concentrated; it means there are more particles of reactant racing around the magnesium, making collisions between the important particles more frequent. This increase in more frequent collisions will increase the rate of reaction. 2) TEMPERATURE- increasing the temperature will increase the rate of reaction. When warming a chemical, kinetic energy is transferred to the chemicals particles, this increase in kinetic energy means the particles will move faster. As the particles are now moving faster this means there are more frequent collisions with the magnesium ribbon. The increased energy of collisions means that there is an increase in collisions that are actually effective. The increase in temperature may not increase the...
