  1. 3.3 Concentration and Rate LO: I understand how to calculate and compare the rate of a reaction.

  2. Aim: To find out how varying the concentration of iodide ions affects the rate of reaction with hydrogen peroxide. About the reaction: H2O2(l) + 2H+(aq) + 2I-(aq) I2(aq) + H2O(l) The concentration of the iodide ions was varied by changing the proportions of water and iodide solution while keeping the total volume constant. The end point of the reaction is when the first hint of the blue/black colour appears. LO: I understand how to calculate and compare the rate of a reaction.

  3. Calculating the rate: 1 = t Relative rate Where, • t = time in seconds (s) • Relative rate is in reciprocal seconds (s-1) Conclusion: The higher the concentration of the iodidie ions, the the rate of the reaction with hydrogen peroxide. faster LO: I understand how to calculate and compare the rate of a reaction.
