Answer Oct 5, 2023 · For example, the reversible reaction of calcium sulfate (CaSO₄) with water is used in the production of gypsum, which is used in construction materials. We Examples of reversible reactions in everyday life include the process of photosynthesis in plants, the formation of lactic acid in muscles, and the baking of bread. Example, for the hypothetical one above: When substances A and B react, they produce substances C and D (forward reaction), and if the condition of reaction is suitable, C and D will in turn combine to give A and B (backward reaction). Two separate reactions are going on simultaneously: the forward reaction, where the reactants become products, and vice versa. After a time, a reversible reaction in a closed system can reach what we call a ‘dynamic equilibrium’. The reaction is reversible, which means that as soon as any water is around, anhydrous copper sulfate will be converted back into the blue hydrated form. Reversible reactions will reach an equilibrium point where the concentrations of the reactants and products will no longer change. The way the equation is written, we are led to believe that the reaction goes to completion, that all the H 2 and the I 2 react to make HI. Mar 16, 2021 · Examples of Reversible Reactions There are a huge number of reversible reactions, so we are going to look at some of the most common example you will come across in your studies.
