Questions & Step-by-Step Solutions
What is the significance of the Faraday constant in electrochemistry?
Step 1: Understand that the Faraday constant is a number that tells us how much electric charge is carried by one mole of electrons.
Step 2: Know that one mole is a specific quantity in chemistry, equal to about 6.022 x 10^23 particles (like atoms or molecules).
Step 3: Learn that the Faraday constant is approximately 96485 coulombs per mole (C/mol).
Step 4: Realize that this constant is important in electrochemistry because it helps us calculate how much electric charge is involved in chemical reactions that involve electron transfer.
Step 5: Use the Faraday constant to relate the amount of substance (in moles) to the total electric charge (in coulombs) in electrochemical processes.
