irreversible reaction
Fast and slow chemical reactions
Slow reactions Chemical reactions that occur very slowly and can take a long time for completion are called slow reactions. Usually covalent compounds are involved in slow reactions. Some reactions can take days, weeks and months to complete; they are called very slow reactions. For example, Milk may take several hours or a day to convert to curd, while it may take even longer for iron to corrode. Rusting of Iron 4Fe + 3O2 -> 2Fe2O3 (Iron) (Oxygen) (Rust – Iron Oxide) Formation of crude oil by a geochemical reaction and disintegration of radium are other examples of ... Read more
