CHEM-ZPN8WL

Given the following redox reaction:

$${ { { Cu }^{ 2+ } }_{ \left( aq \right) } }+{ Zn }_{ (s) }{ { { \longrightarrow { Cu }_{ (s) } } } }+{ { Zn }^{ 2+ } }_{ \left( aq \right) }$$

What process would increase the cell potential?

A

Increasing $\left[ { Zn }^{ 2+ } \right] $.

B

Decreasing $\left[ { Cu }^{ 2+ } \right] $.

C

Removing ${ Cu }_{ \left( s \right) }$.

D

Adding water to the $\left[ { Zn }^{ 2+ } \right] $ solution.
