If at 298 K E ∘ N i 2 + (a q) / N i (s) = − 0.24 V E ∘ F e 2 + (a q) / F e (s) = − 0.44 V then calculate the …
Solved The reduction half reaction for Fe+3/Fe+2 has E= 0.77 - Chegg
WebNov 13, 2024 · The Nernst equation for this cell is. E = E ° − (0.059 n)log10Q = 0 − 0.29log100.1 = + 0.285V. Note that E ° for a concentration cell is always zero, since this would be the potential of a cell in which the electroactive species are at unit activity in both compartments. E ° for a concentration cell is always zero, WebSo that would be positive .54 volts, so positive .54 plus 1.66, plus positive 1.66 volts. So the standard potential for the cell, so E zero cell is equal to .54 plus 1.66 which is equal to 2.20 volts. All right, now that we've found the standard cell potential, we can calculate the equilibrium constant. hillside church of god miami
Calculating the EMF
WebJan 10, 2024 · Type these values into our cell EMF calculator. Calculate the EMF value of the electrochemical cell using the equation: EMF cell = +0.34 V - (-0.76 V) = 1.10 V. Here it is! The electromotive force of the … WebE ∘ cell = (RT nF)lnK For T = 298K, Equation 17.2.13 can be simplified as follows: E ∘ cell = (RT nF)lnK = [[8.314 J / (mol ⋅ K)(298 K)] n[96, 485 J / (V ⋅ mol)]]2.303logK = (0.0592 V n)logK Thus E ° cell is directly proportional to the logarithm of the equilibrium constant. WebTo calculate the standard electrode potential (voltage or emf) for an electrochemical cell (E o (redox) or E o (cell)): Step 1: Write a balanced equation for both the reduction reaction and the oxidation reaction. Step 2: Use a table of Standard Electrode Potentials (Standard Reduction Potentials) to find the value of E o for both reactions smart investor pro cost
