The process of iron being oxidized to iron(II) oxide (rust) is spontaneous. Which of these statements about this process is/are true? (a) The reduction of iron(III) oxide to iron is also spontaneous. (b) Because the process is spontaneous, the oxidation of iron must be fast. (c) The oxidation of iron is endothermic. (d) The energy of the universe is decreased when iron is oxidized to rust.
