What are some chemical reactions that are fast?

Chemical reactions that complete in a very short time, such as less than 10 -6 seconds, they are called fast reactions. Examples: Magnesium ribbon is burnt in the flame of Bunsen burner; it quickly gets combusted with a noticeable spark. Similarly, a neutralization reaction between acids and bases is a fast reaction.

What is an example of a chemical reaction that occurs at a very fast rate?

If we increase the temperature, chemical reactions go faster. For example, effervescent tablets react with water to release carbon dioxide gas.

Why are some reaction very fast?

Reactions in phases that easily mix, such as gases and liquids, occur much faster than reactions between solids. The extent of mixing of the reactants influences the frequency of molecular collisions – if reactants are more thoroughly mixed, the molecules will collide more often and thus react faster.

Is photosynthesis a fast reaction?

Combustion is the fastest and weathering is the slowest. The order of reactivity from fastest to slowest is: combustion, photosynthesis, rusting, weathering. Also plants use photosynthesis to make food and this process has to happen relatively fast but not too fast. Think of some other examples of chemical reactions.

What is fast speed reaction?

The fast reaction is defined as the reaction which takes a shorter time to complete. The fast reaction possesses a high rate of reaction. They possess smaller activation energy. The example of fast reactions are striking a match, burning of petrol in the car engine and so forth.

Is combustion a fast or slow reaction?

Rapid combustion is a form of combustion in which large amounts of heat and light energy are released. This often occurs as a fire. Slow combustion is a form of combustion which takes place at low temperatures. Respiration is an example of slow combustion.

Why is photosynthesis fast?

Increasing the light intensity will make photosynthesis faster. Carbon dioxide level – Photosynthesis can be limited by the level of carbon dioxide. Even if there is plenty of light a plant cannot photosynthesise if it has run out of carbon dioxide.

Is respiration a fast reaction?

Much like other combustion reactions, the glucose needs oxygen to burn, and the products are carbon dioxide and water. Cellular respiration is an example of a slow reaction.
