what kind of reaction is represented here? h2so4 → so3 + h2o synthesis single replacement analysis double replacement
Answer
Answer:
No option is correct. It is a decomposition reaction.
Explanation:
Step1: Recall reaction - type definitions
Synthesis is $A + B\rightarrow AB$. Single - replacement is $A+BC\rightarrow AC + B$. Double - replacement is $AB + CD\rightarrow AD+CB$. Decomposition is $AB\rightarrow A + B$.
Step2: Analyze given reaction
The reaction $H_2SO_4\rightarrow SO_3 + H_2O$ has one reactant breaking down into two products, which is characteristic of a decomposition reaction. There is no option for decomposition among the given choices.
