Question

In a Daniel cell, ______.

Options

• The chemical energy liberated during the redox reaction is converted to electrical energy.

• The electrical energy of the cell is converted to chemical energy.

• The energy of the cell is utilised in conduction of the redox reaction.

• The potential energy of the cell is converted into electrical energy.

Answer 1

In a Daniel cell, the chemical energy liberated during the redox reaction is converted to electrical energy.

Explanation:

Daniel cells, which have an electrode potential of 1.1 V, are used to convert the chemical energy released during redox reactions to electrical energy.

\[\ce{Zn_{(s)} + Cu^{2+}_{ (aq)} -> Zn^{2+}_{ (aq)} + Cu_{(s)}}\]
