To calculate the concentration of [12], use Equation (3) and the concentration of [S₂03²]. In a constant-temperature run described in the procedure section of this experiment, the solution turned blue in 50 s. a) Consider the concentration of [S₂032] in the mixed solution shown in the las column of the table from the previous exercise. Calculate the concentration c [12] final formed in this reaction. b) Calculate the rate of the reaction.
Data Analysis: 1. Create an Absorbance (Y) vs. Concentration (X) graph using data from the six standard solutions above. 2. Perform a linear trendline analysis of your six data points. Display the equation and R² value on the graph with a minimum of 8 decimal places. 3. On the same graph, perform a 2nd order polynomial trendline analysis of your six data points. Display the equation and R² value on the graph with a minimum of 8 decimal places. 4. Turn in your graph as the last page of this report. 5. On a separate piece of paper calculate the concentration of the unknown solution using both the linear and 2nd order polynomial trendline equations (Show all work) 6. Choose the best unknown concentration from #4 above and report it with three significant figures in the unknown data table above.
