Suppose that automobiles were equipped with "thermite" batteries that operate according to the following half-reactions:
2Al + 6OH- Al2O3 + 3H2O + 6e-
Fe2O3 + 3H2O + 6e- 2Fe + 6OH-
What masses of Al and Fe2O3 would be consumed if it takes 15 sec to start your car engine and the battery provides 5.4 A of current to the starter motor. Faraday's constant is 96485 C/mol.
- Mass of Al consumed?
- Mass of Fe2O3 consumed?
