How many faradays of electric charge is required to liberate 5600cm^(3) of oxygen at STP? |
|
Answer» SOLUTION :`O^(2-)to(1)/(2)O_(2)+2e^(-)` or `2O^(2-)toO_(2)+4e^(-)` Thus, 1 mole of `O_(2)`, i.e., 22400 `CM^(3)` requrie 4 faradays of charge. `therefore5600cm^(3)` of `O_(2)` will REQUIRE charge `=(4)/(22400)xx5600=1` faraday. |
