Which of the following statements is true for an electrolytic cell?

Which of the following is $NOT$ a function of a salt bridge?

In the process of obtaining chlorine from brine,the minimum value of $E_{cell}$ should be ....... $V$.

The cell reaction $Cu + 2Ag^{+} \to Cu^{+2} + 2Ag$ is best represented by

Efficiency of a cell with cell reaction under standard conditions is $70\%$. Cell reaction:
$A_{(s)} + B^{\oplus} \longrightarrow A^{\oplus} + B_{(s)}$ ; $\Delta H^o = -551.5 \ kJ$. Calculate standard electrode potential of cell (in $volt$).

The standard cell potential $(E_{\text{cell}}^{\ominus})$ of a fuel cell based on the oxidation of methanol in air that has been used to power television relay station is measured as $1.21 \ V$. The standard half-cell reduction potential for $O_2$ $(E_{O_2 / H_2 O}^0)$ is $1.229 \ V$. Choose the correct statement:
