What are examples of slow reactions?

The slow reaction is defined as the reaction which takes longer time to complete. The slow reaction possesses a low rate of reaction. They possess higher activation energy. The example of slow reactions are rusting of a water pipe, a piece of newspaper turning yellow and so forth.

Which of the following is slow reaction?

Explanation: Rusting of iron is always an slow reaction .

What are the examples of fast and slow reactions or processes that you encounter in our daily lives?

Examples of chemical reactions in everyday life include photosynthesis, rust, baking, digestion, combustion, chemical batteries, fermentation, and washing with soap and water.

Is digestion a slow reaction?

Moderate reactions For example, digestion of food is also a chemical reaction. Neither does it take place in few seconds, nor does it take place in several days. Hence, it is neither fast nor slow reaction, rather it is moderate reaction.

Is rusting fast or slow?

Rusting is a slow reaction.

Which is the slowest chemical reaction?

As to the uncatalyzed phosphate monoester reaction of 1 trillion years, “This number puts us way beyond the known universe in terms of slowness,” he said.

Is cooking a fast or slow reaction?

When food is cooked or when it spoils, many chemical reactions take place. Thus temperature has an effect on how fast chemical reactions take place. That is, the greater the concentration of oxygen, the faster the reaction will go.

What is a reaction rate give an example of a slow reaction and a fast reaction?

Answers. 1. Reaction Rate is the measure of the change in concentration of the disappearance of reactants or the change in concentration of the appearance of products per unit time. 2.

Why are some reactions fast and some slow?

Concentration: If there is more of a substance in a system, there is a greater chance that molecules will collide and speed up the rate of the reaction. If there is less of something, there will be fewer collisions and the reaction will probably happen at a slower speed.

Why does rate of reaction slow?

Reactions usually slow down as time goes on because of the depletion of the reactants. In some cases the addition of a substance that is not itself a reactant, called a catalyst, accelerates a reaction.

Is Neutralisation a fast reaction?

Similarly, a neutralization reaction between acids and bases is a fast reaction. Since, these fast reactions occur between ions, they are also known as ionic reactions. Besides slow and fast reactions, there is another category called moderate reactions.
