Questions & Step-by-Step Solutions
Which of the following statements is true about electrolytic cells?
Correct Answer: Electrolytic cells require an external power source to drive the non-spontaneous reactions.
Step 1: Understand what an electrolytic cell is. It is a device that uses electricity to drive a chemical reaction.
Step 2: Know that some chemical reactions happen naturally (spontaneous) and some do not (non-spontaneous).
Step 3: Realize that electrolytic cells are used for non-spontaneous reactions, which means they need help to occur.
Step 4: Identify that this help comes from an external power source, like a battery or power supply.
Step 5: Conclude that the true statement about electrolytic cells is that they require an external power source to drive these non-spontaneous reactions.
