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?
To calculate the concentration of I2 produced (# of moles of I2 produced / L), you need to know the number of moles of I2 produced in each reaction and the volume of the reaction mixture.
To determine the number of moles of I2 produced, you can use the stoichiometric ratio from the balanced equation. In this case, the stoichiometric ratio is 1:1 between S2O3^2- and I2. So, for every mole of S2O3^2- consumed, one mole of I2 is produced.
Since you have the volume of the reaction mixture (6.6e-3 L), you can now calculate the concentration of I2 produced by dividing the number of moles of I2 produced by the volume of the reaction mixture.
As for the rate of reaction for each flask, the rate is calculated using the rate equation, which relates the rate of reaction to the concentration of reactants. In this case, since you're given the concentration of I2 produced in moles per liter per minute, you can use this value directly as the rate of reaction for each flask. The concentration of I2 produced will not be the same for all 5 flasks unless the reactions are identical. Hence, you'll need to calculate the rate of reaction for each flask separately based on the amount of I2 produced in each flask.
It is not necessary to calculate the order of reaction before calculating the rate for each flask. The order of reaction refers to the dependence of the reaction rate on the concentration of reactants, which can be determined from experimental data. However, for the given question, you already have the concentration of I2 produced, so you can directly use that as the rate of reaction for each flask.
