Answer:
-198 kJ
Explanation:
Hello there!
In this case, as the reaction is not given but we can see that HBr is formed, we can infer that reaction is:
[tex]H_2+Br_2\rightarrow 2HBr[/tex]
Whereas the -72 kJ per moles of HBr are:
[tex]\frac{-72kJ}{2molHBr}[/tex]
Thus, by multiplying by the formed 5.5 moles of HBr, the total energy release is:
[tex]\frac{-72kJ}{2molHBr} *5.5molHBr\\\\=-198kJ[/tex]
Best regards!
