The effect of changing the concentration on the rate of a reaction Research There are 4 ways to alter a reaction: * Surface area- If you break 1 chunk of a solid into smaller particles it will have a larger surface area, this larger surface area will allow more collisions to occur; therefore speeding up the reaction. * Concentration In order for any reaction to happen, those particles must first collide. This is true whether both particles are in solution, or whether one is in solution and the other a solid. If the concentration is higher, the chances of collision are greater. * Temperature When a reaction is heated the atoms are given more energy, therefore move faster. This will make more collisions speeding up the reaction * Catalyst A catalyst provides an alternative route with a lower activation energy. Using less energy means there will more collisions and quicker. Introduction By looking at the variables from my research I...
