ChemistryEasysingle choice

$2 A g^{+} (a q) + C u (s) ⇌ C u^{2 +} (a q) + 2 A g (s)$
The standard potential $E °$ for this reaction is 0.46 V. Which change will increase the potential the most?

Options:

Answer:

Solution:

$E = E ° - \frac{0.059}{2} l o g \frac{[C u^{2 +}]}{[A g^{+}]^{2}}$
The cell potential will increase the most by doubling the concentration of $A g^{+}$ ion.
