1. Assume that 5.00mL of .0500M Na2S2O3 is added to the reaction and that the 150.00 mL solution turns blue in 95 seconds. Calculate the reaction rate in mol I2/Ls. (This is also the rate in mol H2O2/Ls.
2. If a second experiment is done with half as much H2O2 as the experiment in question 1, and the solution turns blue in 180 seconds, what is the order of the reaction with respect to H2O2?
