Question

What are exothermic and Irreversible reactions? Give example of each. ​

Answer 1

Answer:

Here is your answer⤵️

Explanation:

It was believed that all chemical reactions were irreversible until 1803, when French chemist Claude Louis Berthollet introduced the concept of reversible reactions. Initially he observed that sodium carbonate and calcium chloride react to yield calcium carbonate and sodium chloride; however, after observing sodium carbonate formation around the edges of salt lakes, he realized that large amount of salts in the evaporating water reacted with calcium carbonate to form sodium carbonate, indicating that the reverse reaction was occurring.

Hope its help..⤴️

Answer 2

Answer:

Reactions in which the reactants convert to products and where the products cannot convert back to the reactants is called irreversible.

Example : boiling an egg.

Exothermic reactions are reactions that release energy in the form of heat.

Example : rusting of iron, and freezing of water.
