Question

Phase change reaction in Daniell cell is an example of?

• A. Isochoric process
• B. Reversible process
• C. Cyclic process
• D. Irreversible process

Answer 1

Answer:

B. Reversible process

The phase change reaction in a Daniell cell is an example of a reversible process. This is because the reaction can proceed in both forward and reverse directions depending on the external conditions. A Daniell cell is the best example of a galvanic cell which converts chemical energy into electrical energy. The Daniell cell consists of two electrodes of dissimilar metals, Zn and Cu; each electrode is in contact with a solution of its own ion; Zinc sulphate and copper sulphate respectively.
