Question

why burning of alcohol take place very quickly whereas rusting of iron proceeds slowly?​

Answer 1

Answer:

Reactions that take a while are slow reactions and those which occur within a few seconds are fast reactions.

The rusting of iron, the fermentation of sugar into alcohol, the chemical weathering of rocks (breaking down of rocks), the photosynthesis process in plants, coal formation are slow reactions.

Whereas neutralization reaction of a strong base like sodium hydroxide and strong acid like HCl is a fast reaction .

Answer 2

Explanation:

We now know that it's the alcohol vapor that catches fire, not the liquid, just like with gasoline. More vapor comes off the alcohol as the alcohol heats up, making it easier for it to light. Colder alcohol means less vapor, which means less chance for flames. The vapor also impacts what you can use as a lighter, in the other handAlloying – Since Rusting of Iron is a chemical process that happens because the metal is attaining more stable chemical state, alloying (mixing) the iron with other stable metals or alloys can slow down the process of rusting.
