Considering the activity series given for nonmetals, what is the result of the below reaction? Use the activity series provided. [tex]F > Cl > Br > I[/tex]
[tex]Br_2+NaF \rightarrow[/tex]
A. no reaction
B. [tex]Na + FBr _2[/tex]
C. [tex]NaBr + F _2[/tex]
D. [tex]Na _2 F+ Br _2[/tex]
Answer (2)
The activity series indicates the reactivity of nonmetals: Cl > Br > I"> F > Cl > B r > I .
Bromine ( B r 2 ) is reacted with sodium fluoride ( N a F ).
Since fluorine is more reactive than bromine, bromine cannot displace fluorine from N a F .
Therefore, the reaction does not occur: n ore a c t i o n .
Explanation
Analyzing the Activity Series and Reaction We are given the activity series for nonmetals: Cl > Br > I"> F > Cl > B r > I . This means that fluorine (F) is the most reactive, followed by chlorine (Cl), then bromine (Br), and finally iodine (I). The reaction we need to analyze is:
Writing the Reaction B r 2 + N a F →
Determining Displacement In this reaction, we want to see if bromine ( B r 2 ) can displace fluorine (F) from sodium fluoride ( N a F ). According to the activity series, a more reactive nonmetal can displace a less reactive nonmetal from its compound. Since fluorine is more reactive than bromine, bromine cannot displace fluorine from sodium fluoride.
Concluding the Reaction Outcome Therefore, the reaction will not occur.
Stating the Final Answer The result of the reaction is no reaction.
Examples
The activity series is used in various industrial processes, such as water purification and metal extraction. For example, in water purification, chlorine is often used to disinfect water because it is more reactive than bromine and iodine, allowing it to effectively kill bacteria and viruses. Similarly, in metal extraction, more reactive metals are used to displace less reactive metals from their ores, enabling the isolation of pure metals.
The reaction between bromine ( B r 2 ) and sodium fluoride ( N a F ) does not occur because bromine cannot displace fluorine due to its lower reactivity. Therefore, the result is no reaction. The chosen option is: A. no reaction.
