WebPerform calculations involving the relations between cell potentials, free energy changes, and equilibrium. Use the Nernst equation to determine cell potentials under nonstandard … Web(e) Determine the value of the standard voltage,E°, for the cell. E° = (−0.76 V) − (−1.66 V) = 0.90 V One point is earned for the correctE°. (f) Indicate whether the value of the standard free-energy change, ΔG°, for the cell reaction is positive, negative, or zero. Justify your answer. ΔG° is negative sinceE° is positive and DGn∞=-E°.
WebIf we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76.

WebThe relationship between cell voltage, E, and ΔG for the cell reaction is given by the following equation. ( 3 ) ΔG = − nFE, or E = − ΔG / nF. The nF term is related to the coulombs of negative charge transferred in the balanced redox reaction. The number of moles of electrons transferred is given by n. F is Faraday's constant, which is ... WebQuestion: Calculate E∘cell for each of the following balanced redox reactions. Part A: O2(g)+2H2O(l)+4Ag(s) → 4OH−(aq)+4Ag+(aq) Part B: Br2(l) + 2I−(aq) → 2Br−(aq) + I2(s) Part C: PbO2(s)+4H+(aq)+Sn(s)→Pb2+(aq)+2H2O(l)+Sn2+(aq) Part D: Which of the reactions are spontaneous as written. Check all that apply
WebE_cell = E_standard_cell_potential - (RT)/ (nF) * ln ( [products]/ [reactants]) So it depends on the sign of the log term. If concentrations of the products are greater than the concentrations of the reactants, then the cell potential will become more negative as temperature increases. (the log bit keeps the second term negative).
