An electrochemical cell as an electrolytic cell
Answer: An electrochemical cell can indeed function as an electrolytic cell when an external voltage source is applied to it. In an electrochemical cell, spontaneous chemical reactions generate an electric current, while in an electrolytic cell, an external electric current drives a non-spontaneous chemical reaction.
When a voltaic (galvanic) cell operates spontaneously, it generates electrical energy, but an electrolytic cell requires an external electric current to drive a non-spontaneous chemical reaction. The energy input in the form of electricity causes the non-spontaneous reaction to occur.
In summary, an electrochemical cell can be used as an electrolytic cell when an external voltage is applied to it to drive a non-spontaneous reaction. This process is essential in various industrial processes and technologies, such as electroplating, electrolysis, and the production of various chemicals through electrolysis.
