6. To purify water which has iodine in it, one can use extraction with CCl4. The equati can be written as I2 (aq) S 2 (CCL4). What is the partition coefficient? e. K=[1;L, b. K = c. K=- d. 1 a. K = - P 7. Consider the unbalanced chemical equation CACO3 + H3PO4 smallest integer coefficients, the coefficient for CO2 is Ca3(PO4) 2 + CO2 + H2O. When the reaction is balanced with a. 1 b. 3 с. 5 d. 7 e. none of these

2. Set the two equations equal and isolate In Ksp on one side of the equals sign by dividing both sides by (-RT). AG=RT'In Ksp=AH-TAS/-RT AG=In KSR=AH-TAS/-RT| 3. Create a graph using Excel plotting In Ksp on the y-axis and 1/T (make sure the units for temperature are Kelvin) on the x-axis. I In KSP 0 0.0029 -0.5 -1 -1.5 -2 -2.5 -3 -3.5 -4 -4.5 -5 0.003 0.0031 0.0032 1/T 0.0033 0.0034 0.0035 y=-2738x+5.075 R² = 0.9845 0.0036 a. Use the value obtained for the slope of the graph to solve for AH° using the equation derived in Question 2.
