Characteristics of chemical reactions are certain characteristics that tell us whether a chemical reaction has occurred or not.
Some important characteristics of chemical reactions are given below :
I was wondering whether all chemical reactions can be identified by one or more of these characteristics. Since there is an extremely wide range of chemical reactions, I think that these are just the major characteristics of chemical reactions and there may exist some reactions that exhibit none of these characteristics.
Am I right about this? If yes, what are some examples of chemical reactions that show none of these characteristics?
