The potential of a voltaic cell (Ecell) is calculated based on several variables. Identify from the list below the values you would need to determine the cell potential. a. number of electrons, n
b. density of metal, rho
c. coefficients from balanced redox equation (various)
d. temperature, T
e. Gibbs free energy change, ΔG
f. enthalpy change, ΔH
g. reduction potential, Ered

number of electrons, n

Gibbs free energy change, ΔG

temperature, T

coefficients from balanced redox equation (various)

Explanation:

The standard electrode potential of a cell can be obtained from;

∆G°= -nFE°cell

Also;

E°cell= RTlnK/nF

Where;

∆G°= standard free energy of the cell

n= number of electrons transferred

F= Faraday constant

E°cell= standard cell potential

R= universal gas constant

T= temperature

K= equilibrium constant
