Vedclass · Answer

(C) The thermodynamic efficiency of a cell is defined as the ratio of the electrical work done by the cell to the change in enthalpy of the reaction.Electrical work done by the cell is given by $W_{elec} = nF E_{cell}$.The total energy available from the reaction is the enthalpy change,$\Delta H$.Therefore,the efficiency $\eta = \frac{nF E_{cell}}{\Delta H}$.
