WebbE cell = E° cell – (RT/nF) lnQ. E cell is the cell potential under non-standard conditions, while E° cell is the cell potential under standard conditions. R is the universal gas constant, F is Faraday’s constant, and Q is the reaction quotient. The value of RT/F = 0.0257 V. Therefore, the Nernst Equation boils down to.

WebbE cell = oxidation potential + reduction potential. Since the tabulated standard electrode potentials are reduction potentials, the one which is most negative will need to be reversed in sign to get its oxidation potential. When that is done, it is clear that the theoretical standard cell potential for the zinc-copper cell is 1.10 volts. Webb4 okt. 2024 · This is a product of the number of electrons transferred per unit of the overall reaction, the cell potential in volts, and the Faraday constant (96 485 C/mol). The theoretical cell potential depends on the composition of the reaction mixture and can be calculated using the Nernst equation. Tell Us What You Think!

Webb5 dec. 2024 · A properly designed solar cell has to be optically thick (i.e. to absorb all or most of the incident sunlight) and electronically thin (i.e. to collect the photoexcited electron-hole pairs with little or no losses). These two requirements lead to an optimal thickness that maximizes the efficiency.
