Aim To find out how changing the temperature affects the rate of reaction. Background Information The rate of reaction is the speed in which the reaction takes place. Many things can affect the rate of reactions. The more particles there are in a given space the more likely it is that they will bump into each other. The rate increases as particles hit each other more frequently giving more opportunities for a reaction to occur. The particles gain more energy therefore gain speed and particles are then more likely to collide. Equation for sodium thiosulphate Na2S203 + 2HCL 2Nacl + H20 + SO2 + S (aq) (aq) (aq) (l) (g) (s) These four variables will affect the rate of reaction TEMPERATURE: - by increasing the temperature, the atoms are given more energy to move, and thus they move faster and strike other atoms harder SURFACE AREA: - if a substance had a large surface area,...
