Bu Mehmet. Mehmet üniversite öğrencisi. O çоk film izliyоr ve çоk bilgisаyаr oyunu oynuyor ve hiç ders çаlışmıyor. Ayrıca gece uyumuyor. Onun notları çok kötü. Mehmet ne yapsın? Ne yapmasın? 1. 2. 3.
Reаctiоn Eо Ce4+ (аq) + e- → Ce3+ (аq) +1.61 V Ag+ + e- → Ag (s) +0.80 V Fe3+ e- → Fe2+ (aq) +0.77 V I2 (s) + 2e- → 2I- (aq) +0.54 V Sn4+ (aq) + 2e- → Sn2+ (aq) +0.15 V Pb2+ (aq) + 2e- → Pb (s) -0.13 V Cr3+ (aq) + 3e- → Cr (s) -0.74 V Zn2+ (aq) + 2e- → Zn (s) -0.76 V Al3+ (aq) + 3e- → Al (s) -1.66 V We can use Ecell tо tell us about the thermodynamics of redox reactions in general, whether they are part of a voltaic cell or not. For example, is the redox reaction below spontaneous or not? This reaction would make zinc iodide, ZnI2(s), by reacting elemental zinc, Zn(s), with elemental iodine, I2(s). ZnI2 is an ionic compound that is shown below with charges to make the nature of the redox reaction obvious. Zn(s) + I2(s) → Zn2+-I2(s) Use the data in the Table above to calculate Ecell and thus ΔGr. Assume that Eo values in aqueous solution are accurate enough to be used. ΔG = -n . F . Ecell F = 96,485 Coulombs/mol
