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!
