In left half cell of galvanic cell,......takes place?

• Reduction

• Oxidation

• Both

• None

Answer explanation

In galvanic cell oxidation takes place in left half cell while reduction takes place in right half cell.

In electrolytic cell......... Oxidation-reduction reaction takes place?

• Spontaneous

• Non-spontaneous

• Both

• None

Answer explanation

In electrolytic cell always spontaneous reaction takes place,beacuse energy is required to start up a reaction.

• Electrolytic cell

• Galvanic cell

• Both

• None

Answer explanation

Non-spontaneous oxidation-reduction reaction takes place in galvanic cell.
