Question
Two important characteristics of batteries are their cell potential and the total charge that they can deliver. For any specific battery, the cell potential and total charge depends on the chemical reactants ____________ and ____________, respectively.
1. temperature concentrations
concentrations temperature
3. amounts concentrations
4. amounts temperature
5. concentrations amounts
1. temperature concentrations
2.concentrations temperature
3. amounts concentrations
4. amounts temperature
5. concentrations amounts
Explanation / Answer
According to Nernst equation,Eocell=Eo -((RT)/(nF))*lnK
Where
R-gas constant
T-temperature
N-number of electrons
F-faraday
K-equilibrium constant (depends on concentration)
The cell potential and total charge will depend upon the concentration of reactants and temperature.
Therefore option (2) is correct.
