ChemistryEasysingle choice

Consider the following $E °$ values:
$E °_{L i^{+} | L i} = - 3.05$ $V,$ $E °_{C u^{2 +} | C u} = + 0.34$ $V$
Under similar conditions, the potential for the reaction $C u + 2 L i^{+} \to C u^{2 +} + 2 L i,$ is

Options:

Answer:

Solution:

$E_{Cell}^{o} = {(E_{red}^{o})}_{Cathode} - {(E_{red}^{o})}_{Anode}$
Given
$E °_{L i^{+} | L i} = - 3.05$ $V,$ $E °_{C u^{2 +} | C u} = + 0.34$ $V$
For the reaction, $C u + 2 L i^{+} \to C u^{2 +} + 2 L i,$
$E ° = (- 3.05) + (- 0.34) = - 3.39$ $V$
