Critical Thinking: Effect on Cell Potential

CHEM-@Y0FS4

Given the following redox reaction:

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

Choose answers describing a process that will DECREASE the cell potential.

Select ALL that apply.

A

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

B

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

C

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

D

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

E

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

F

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

G

Increasing mass of ${ Cu }_{ \left( s \right) }$.

H

Increasing mass of ${ Zn }_{ \left( s \right) }$.
