I believe this would be a chemical compound, yet it is not one of the options present.
The relationship of a pair of compounds could be one between these options :
- Structural isomerisms
happened when molecules with same molecular formula have bonded together in different orders
- Stereoisomerism
Happened when two or more compounds differing only in the spatial arrangement of their atom
hope this helps
Answer:
the energy barrier that must be surmounted in order for the reactants to transform into products.
Explanation:
When we draw a reaction profile, there is always a hump that is found between the reactants and products. This hump is called the activation energy.
The activation energy of a reaction stands as a sort of barrier between reactants and products which must be surmounted before the reactants are converted into products.
Only reactants that possess the activation energy can be converted from reactants to products.
