How does the Temperature affect the Rate of Reaction between Calcium Carbonate and Acid? PLANNING Introduction: We are investigating how the temperature affects the rate of reaction between Sodium thiosulphate and acid. This project will involve 4 parts, which in them will have separate sub-headings. We will be doing the planning, obtaining evidence, analysing and concluding and finally evaluating. All the different aspects of rates of reaction will also be taken into account. E.g. Other factors and how to make the test fair. The symbol equation for the reaction we are investigating is: Na2S203(aq) + 2HCL(aq) 2NaCl(aq) + H2O(l) + S(s) + SO2(g) The word equation for the reaction we are investigation is: Sodium thiosulphate + Hydrochloric acid Sodium Chloride + Water + Sulphur + Sulphur dioxide The rate of reaction can be found with the formula below: Reaction Rate = Change in amount of a substance Time Taken Theoretical Background: The rate of reaction can be calculated as with...
