Question

In an electrochemical cell, there is the conversion of :

• A. Electrical energy into heat energy
• B. Chemical energy into electrical energy
• C. Chemical energy into heat energy
• D. Mechanical energy into heat energy

Answer 1

Answer:

B. Chemical energy into electrical energy

• In an electrochemical cell, there is the conversion of:

  • Chemical energy into electrical energy (in a galvanic or voltaic cell, such as a battery during discharge).

  • Electrical energy into chemical energy (in an electrolytic cell, such as during the charging of a battery or electroplating).
