$E^{\circ}$ values of $Mg^{2 +} / Mg$ is -2.37 volts of $Zn^{+ 2} / Zn$ is -0.76 volt and $Fe^{+ 2} / Fe$ is -0.44 volt. Which of the following statements is correct?

Options:

Answer:

Solution:

For $Zn + 2 Fe^{+ 2} \to Zn^{+ 2} + 2 Fe E_{cell}^{o} = - 0.44 + 0.76 = + ve$ and hence, the reaction is spontaneous.
