A scientist is adding oxygen to iron in a chemical reaction to create rust. At what point during this reaction will the oxygen and iron quit making rust?

What type of chemical reaction is rusting of iron?

Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
