⚡ Previous NEET Electrochemistry Question — CHALLENGE YOUR CONCEPTS! ⚡
Can you solve this without looking at the options? 👀🔥
A simple-looking electrochemical cell question—but the real challenge is correctly applying:
🔹 ΔG° = −nFE°cell
🔹 Number of electrons transferred (n)
🔹 Sign of Gibbs free energy
🔹 Cell notation & spontaneous reaction
💥 Previous NEET Question | Electrochemistry | Gibbs Energy
Comment your answer: A, B, C or D — before checking the solution! 🧠⚡

Never add E° directly! 🛑⚡

​Did you fall into this classic Electrochemistry trap? 🕳️ Remember, standard cell potential E° is an intensive property—it depends on the nature of the reaction, not the amount, so you can't just add or subtract potentials directly! Instead, always route your calculations through Gibbs Free Energy (∆G°), which is an extensive property.
