How much Mol S2O32- consumed and how much I3- was produced?
Transcribed Image Text:Data Tables for Kinetics Lab
There are a BUNCH of calculations for this lab. I've organized the data into the table below. You will need to read the table in the.
procedure VERY carefully to make sure you're using the correct volumes and concentrations for each calculation below.
Many of the points for this lab will come from the submission of this data sheet with the calculations and the two graphs! If your
data is incorrect on these tables, your graphs will be incorrect and you will not get the correct values for the order of the reaction!
Make sure you know which sulfur compound is which!
Thiosulfate (from the procedure) is S₂0,²
Persulfate (from the procedure) is also called peroxosulfate or peroxodisulfate and is $₂O²

Follow-up Question
I also need help filling out these.
![Use the Mol S2032 consumed and Mol 13 produced from the table above for the calculations in Table 2
Since you are working with moles from Table 1, you'll need to divide by total volume in liters to get the [S₂032] and [13].
Since you are working only with M and V for the persulfate [S2082] and iodide [1] and just diluting solutions, you can use mL
in your M₂V₁-M₂V₂ calculations. Or you can use L, just use the same unit for both!
