Q30 / 180 · COMEDK 2014 · Chemistry

In a electrochemical cell, the reaction will be feasible when

  • Correct answer
    A
    $\Delta G=-$ ve, $E=$ +ve
  • B
    $\Delta G=+$ ve, $E=-$ ve
  • C
    $\Delta G=0, \quad E=$-ve
  • D
    $\Delta G=0, \quad E=0$

Solution

In a electrochemical cell, the reaction will be feasible when, $\Delta G$ is - ve which is possible only when $E$ is tre as $\Delta G=-n F E$.

Hence, the correct answer is option: 'A'.
