Give me some examples of slow and fast reaction?

Is this homework?

The question is too brief and not at all clear as to what you want to know.

Yea this is homework

What subject? Psychology? Physics? Home ec? Chemistry?

I tell my son to make his bed. His reaction is slow. The next day I tell my son to make his bed and, when he is finished, he will get three chocolate chip cookies. His reaction is fast.

Chemistry

Well, think about your everyday life...

A bomb explosing is a typical example of a fast reaction.
Rusting is a typical slow reaction.

Rusting doesn't occur in the blink of an eye, but explosives? I think they occur faster than you can blink :D

Other examples of fast reactions:
In car engines, where the fuel is ignited and it burns rapidly producing much heat.
In fluorescent light bulbs, the gas in the bulb is ionised (becomes charged) and emits light.
The thermit reaction, which is used to remove rust from train rails. Aluminium powder is just placed on the rusty rail, and it heats up quickly forming aluminium oxide and converting the rust into iron.
Sodium + water. The piece of sodium reacts vigorously with the water, dazzling onto the surface and sometimes burns with a yellow flame.

Other examples of slow reactions:
The rotting of food. Your food does not rot in a matter of seconds, does it? ;) It's a chemical reaction, yes!
In cooking. The food does not cook that quickly... so people has been devising ways to speed up cooking, such as pressure cooker, ovens, etc.
'Respiration in your body'. (You may need to refer to respiration in biology to understand the process better). Imagine if you just used all the energy in your food in a matter of seconds... you'd need to constantly eat to be always able to have available energy!

There are so many more, you only need to think about it for a little while :)

Thank u

Just avoid to use texting language, that often is difficult to guess the real meaning behind... and makes an impression that you are lazy ;)

You're welcome!

Next time, be more precise in your question. :)
