Homework Help: Chemistry(please help)

Posted by Hannah on Tuesday, February 28, 2012 at 1:03am.

I have to calculate the concentration of I2 produced (# of moles of I2 produced / L) based on the stoichiometric ratio in the following equation.

2S2O3^2- + I2 -> 2I^- + S4O6^2-






So I got 6.6e-3 L*min for the amount of I2 produced. Now I have to calculate the rate for each of the 5 flasks used, so is the answer going to be the same for all 5?? It says to calculate the rate of reaction for each run using # of moles of I2 produced/L*min as the unit.

Do I need to calculate the order of reaction before I calculate the rate for each of the 5 flasks used?
