Line three of each entry is logK for the reaction shown in lines 1 and 2. Log K is tabulated at the following temperatures (degrees C) 25, 50, 100, 150, 200, 250, 300, 350 at pressures of the H20 1/v curve in P-T space. 1.0 Cu+2 + 0.5 H20 + 0.125 HS- = 1.125 H+ + 0.125 SO4-- + 1.0 Cu+ Problem 6.0 redox and adding equilibria [5] In problem 5, you already did the following: Wrote a balanced redox equation using O2 (gas) for reduction of Cu++to Cu+. Wrote a balanced redox equation using aqueous HS- and S042- for reduction of Cu++to Cu+. Wrote a balanced redox equation using aqueous HS- and S042- for reduction of Cu++(aq) to Cu degree (solid). Now, for problem 6, for each of the three reactions above, use SOLTHERM to determine log K's at 25 degree and 100 degree C. To determine the log K's for the above reactions using SOLTHERM, you will need to find equilibria in SOLTHERM that you can add and subtract to corne up with the net balanced reactions that you have written. Notice that "subtracting" is the same as adding the inverted reaction expression. This is usually easiest. Balancing may entail multiplying some SOLTHERM equilibria by factors of 2, 3, -1, or .5, for example, so that, when added they corne to the reactions you want. Recognize that once you have a scheme for equilibria addition, the overall log K is the sum of log K's for the component equilibria, adjusted appropriately by multiplying factors or reaction inversion.Explanation / Answer
The mass per repeating unit of PET is 1992.2g/mol, because PET is a polymer that contains a large molecule composed of repeating structure units. Each repeating unit is going to react with each OH-.
