Predict whether the following reaction would proceed spontaneously as written 298K.


Co + Fe2+ -> CO2+ + Fe


Given that [Co2+]=0.15M and [Fe2+]=0.68M


Co2+ + 2e- ->Co E°=-0.28V


Fe2+ + 2e- -> Fe E°=-0.44

What is the potential of a cell made up of Zn/Zn2+ and Cu2+/Cu, half cell at 76°c. If [Zn2+]=0.25M and [Cu2+]=0.15M


Given that Zn/Zn2+ E°=-0.76V, Cu2+/Cu E°=0.34



A zinc electrode is submerged in an acidic 0.80M Zn+ solution which are connected by salt bridge to a 1.30M Ag+ solution containing a silver electrode. Determine the initial voltage of the cell at 298k



Given that:



Zn/Zn2+ E°=0.76V



Ag+/Ag E°=0.80V
