How does temperature affect the rate of reaction between either; a) 250 cm ³ of sodium thiosulphate solution and 50 cm ³ of hydrochloric acid, or b) 20 cm of magnesium ribbon and 250 cm ³ of hydrochloric acid? Background knowledge. There are many factors, which can affect the rate of reaction; these include the effect of temperature, concentration, surface area, pressure of gases and the effect of a catalyst. Temperature: In a cold reaction the particles move slowly so they don't collide with each other as much. When they do collide the collisions will be less successful as they have less energy. If the reactants are heated they will have more energy, the particles will move faster and collide more so more collisions will be successful. LOW TEMPERATURE. HIGH TEMPERATURE. Concentration: If the reactants are in low concentration the particles are spread out and will collide less often and less successfully....
