Question

Why does the rate of rust become fast in rainy season?

Answer 2

Answer: Because of High level of humidity in the air.

Explanation:

Rusting is basically a chemical reaction that happens to the iron in the presence of water. This reaction can be written as

4Fe + 3O2 → 2Fe2O3.

During other seasons, the moisture content in the air is comparatively lesser. In rainy season, the humidity is very high and more water vapors are present in air. Therefore the rate of rusting is high in rainy season.
