... THE RATES OF REACTION OF METALS WITH ACID AIM OF EXPERIMENT 1 To determine whether the rate of the reaction changes as the concentration is varied. AIM OF EXPERIMENT 2 To find out what effect changing the type of acid used (strong or weak) will have on the activation energy. SCIENTIFIC KNOWLEDGE Factors, which have an effect on the rate of a reaction Temperature - when the temperature is increased the rate of the reaction will decrease. This is because at higher temperatures molecules have more energy to move and collide with enough energy to react, so the reaction will be quicker. Concentration- if the concentration is increased then the rate will decrease. This is because there are more molecules within the same volume so they are more likely to collide and react, so the reaction will happen more quickly. Surface area - When the surface area of a substance is increased the rate of that reaction
