What does 'FAT CAT' signify in terms of electron flow during electrochemical reactions?

• A. Electrons flow from Cathode to Anode
• B. Electrons flow from Anode to Cathode
• C. Electrons flow in both directions
• D. No electron flow occurs

Answer: (B)

The acronym 'FAT CAT' is a mnemonic used to remember the direction of electron flow in electrochemical reactions. Specifically, it stands for "Electrons flow from Anode to Cathode." This is a fundamental concept in electrochemistry: during a redox reaction, oxidation occurs at the anode, where electrons are released, and these electrons then travel to the cathode, where reduction takes place. Understanding this electron flow is crucial for grasping how electrochemical cells work, such as galvanic (voltaic) cells and electrolytic cells. By recalling 'FAT CAT,' one can easily remember that electrons move away from the anode (where they are generated) towards the cathode (where they are consumed), reinforcing the principle of charge conservation and energy transformation in these systems.
