Give an example of a fuel cell and write the cathode and anode reactions. |
|
Answer» Solution :HYDROGEN CELL `[H_(2)-O_(2)]` is an example of fuel cell. The REACTIONS are given as under: `{:("Anode", H_(2)(g) + 2OH^(-)(q) to 2H_(2)O(l) + 2E^(-)xx 2),("Cathode", O_(2)(g) + 2H_(2)O(l) + 4e^(-) to 4OH^(-)(aq)), ("Net reaction", 2H_(2)(g) + O_(2)(g) to 2H_(2)O(l)):}` |
