In Experiment M you studied the reaction: S2Og²- + 2l¯ → 2SO42- + 12 The reaction time was monitored by the "iodine clock reaction": 2S2032- + 12→ 21¯ + S406²- When the above reaction was carried at 22°C (using the same concentrations) with a trace of copper sulfate, the time for the reaction decreased because: The rate constant decreases due to the presence of the copper ions The rate constant decreases due to the presence of the sulfate ions The copper ions provide an alternative path for the reaction of S20g²- + 2I° The copper ions increase AH so more molecules of S2032- could react OThe copper ions provide an alternative path for the reaction of S2O3²- with I2
