What happen in the transitional zones?

Answer 1

When you are performing a chemical reaction, there are often so called 'transitional phases' which, reaction-wise, occur prior to your final product. These are stages that are very short-lived, but who are extremely crucial to the overall success of the reaction.

Picturing an imaginary hill is a good way to think about transitional phases:

Imagine you have your reactants at the foot of the hill at first. To react, you will have to get past a certain point of the hill (the peak) to get over to the other side. In a simple reaction: a + b → c (with no consent to the reaction's coefficient variables), this would mean that you on the left side of the hill have a + b and on the right side have c. The transitional phase or transition state of the molecule(s) involved in the reaction is the peak. At this peak, we might have a scenario in which the molecule(s) have begun structural changes or other conformational changes in order to "prepare" for the next step of the reaction (which in our case is the final step, seeing as we are picturing a one-step reaction). Thus, it is in the transitional phase much of the important chemistry of a reaction occurs.

If you have multiple-step reactions, which yields several products, it gets somewhat more complex, but the "hill"-concept is still viable when regarding these type of reactions as well. Just imagine there are several bumps on the way up and/or down the hill (depending on the reaction), and the middle of each bump represents a transition state which the reaction must overcome to proceed. If there is a greater valley between two bumps, there is a greater likelihood of the reactants getting stuck in there, very much as how a ball might get stuck if you roll it in a u-shaped track. This is a known problem for chemists and is considered to be something of a trap, energy-wise; the reactants have come part-way to the final product, but gets stuck, seeing as there simply is too much energy needed to progress to the next phase. If you think through the experiment though, this is usually avoidable (usually solvable through picking a different reagent, or a particular catalyst).

As said, these transitional states are usually so fast we do not observe them, although they are measurable. At last, knowing the different transitional phases of a reaction means you are able to understand the reaction much better and it might also help you as you deal with more complex reactions where you might receive side-products which you are not interested in - the choice of a different reactant, which is more likely to undergo a certain transition state that works in favor to obtain the sought for product will give you better results.

Answer 2

Transitional zones exist where different ecosystems meet, leading to unique environmental conditions and species diversity. These areas often experience mixing or blending of characteristics from neighboring ecosystems, fostering the development of specialized adaptations and species. Human activities can impact these zones and lead to habitat fragmentation and loss of biodiversity.
