To determine the classification of the given chemical reaction [tex]\(AB + C \rightarrow CB + A\)[/tex], let's analyze the reaction step by step.
1. Identify the Reaction: In this reaction, a compound [tex]\(AB\)[/tex] reacts with an atom or molecule [tex]\(C\)[/tex]. As a result, part of the compound [tex]\(AB\)[/tex] is replaced by [tex]\(C\)[/tex], forming a new compound [tex]\(CB\)[/tex] and releasing [tex]\(A\)[/tex] as a separate entity.
2. Classify Based on Reaction Type:
- Synthesis: This type of reaction involves combining two or more reactants to form a single product. An example would be [tex]\(A + B \rightarrow AB\)[/tex]. Clearly, this does not describe our reaction, so synthesis is not the correct classification.
- Polymerization: This reaction type involves small molecules called monomers combining to form a larger molecule or polymer. Our reaction does not involve the formation of large chains or polymers. Thus, polymerization is not applicable here.
- Decomposition: This reaction involves breaking down a single compound into two or more simpler substances. An example of this would be [tex]\(AB \rightarrow A + B\)[/tex]. Our reaction involves two reactants combining and swapping parts, so decomposition does not fit.
- Oxidation: Oxidation reactions involve the transfer of electrons, typically associated with the gain of oxygen or the loss of hydrogen in a compound. Our reaction is not specifically an electron transfer reaction, so it does not classify as oxidation.
- Replacement: Also known as a single replacement reaction, this type involves one element being replaced by another in a compound. An example is the general form [tex]\(A + BC \rightarrow AC + B\)[/tex]. Our given reaction [tex]\(AB + C \rightarrow CB + A\)[/tex] fits perfectly into this category, as [tex]\(C\)[/tex] replaces [tex]\(A\)[/tex] in the compound [tex]\(AB\)[/tex].
Given these classifications, the reaction [tex]\(AB + C \rightarrow CB + A\)[/tex] is best described as a replacement reaction.
Therefore, the correct classification for the reaction is "replacement."
