To classify the given chemical reaction [tex]\( AB + C \rightarrow CB + A \)[/tex], we need to identify the type of reaction taking place. Let's analyze the components:
1. Initial State (Reactants):
- We start with AB (a compound) and C (an element).
2. Final State (Products):
- After the reaction, we obtain CB (a new compound) and A (an element).
Observing this exchange, we can see that the element C displaces A in the compound AB to form CB and free element A. This type of reaction involves one element being replaced by another in a compound.
The correct term for this type of reaction is a replacement reaction (also known as a single displacement reaction). Here, one element (C) replaces another element (A) in the compound (AB), leading to the formation of CB and A.
Based on the provided options:
- Synthesis: This involves combining two or more substances to form a more complex product. This does not match the reaction type.
- Polymerization: This involves combining small molecules to form a polymer. This does not match the reaction type.
- Decomposition: This involves breaking down a compound into two or more simpler substances. This does not match the reaction type.
- Oxidation: This involves the transfer of electrons and changes in oxidation states, often involving oxygen. This does not match the reaction type.
- Replacement: This involves an element displacing another element in a compound, which perfectly matches the reaction described.
Therefore, the given chemical reaction [tex]\( AB + C \rightarrow CB + A \)[/tex] is best classified as a replacement reaction.
