WebQuestion The standard cell potential (E°cell) for the reaction below is +0.63 V. The cell potential for this reaction is ________ V when [ Zn2+] = 1.0 M and [Pb2+] = 1.5⋅10−4. Pb2+ (aq) + Zn (s) →Zn2+ (aq) + Pb (s) Expert Solution Want to see the full answer? Check out a sample Q&A here See Solution star_border WebTo calculate the cell potential (E cell) for this reaction, we need to use the Nernst equation: E c e l l = E ° c e l l − ( R T n F) × ln ( Q) where: E° cell is the standard cell potential R is the gas constant (8.314 J/ (mol*K)) T is the temperature in Kelvin n is the number of electrons transferred in the reaction F is the Faraday ...

Cell Potential: Meaning, Condition & Formula StudySmarter

WebWhen the half-cell X is under standard-state conditions, its potential is the standard electrode potential, E° X.Since the definition of cell potential requires the half-cells function as cathodes, these potentials are sometimes called standard reduction potentials.. This approach to measuring electrode potentials is illustrated in Figure 36.2, which … WebApr 16, 2015 · So the question is essentially asking what concentrations are needed for your cell to have the standard potential. Again looking at the Nernst equation, you can solve for the reaction quotient Q when E cell = E cell ∘ E cell = E cell ∘ − R T n F ln Q E cell − E cell ∘ = 0 = R T n F ln Q ln Q = 0 Q = 1 spooky story for kids youtube

To get a positive cell potential (spontaneous process) the reaction quotient Q must be <1. Q < 1 in this case, so the process is spontaneous.
