Chapter 4, Problem 53E

The process of iron being oxidized to make iron (III) oxide (rust) is spontaneous. Which of these statements about this process is/ are true?

  1. The reduction of iron (III) oxide to iron is also spontaneous.
  2. Because the process is spontaneous, the oxidation of iron must be fast.
  3. The oxidation of iron is endothermic.
  4. Equilibrium is achieved in a closed system when the rate of iron oxidation is equal to the rate of iron (III) oxide reduction.
  5. The energy of the universe is decreased when iron is oxidized to rust.
