Answer:

In fact you would measure this process.............

Explanation:

And it's not a measurement that I would like to conduct. Liquid bromine (and even worse bromine vapour) are among the most corrosive substances you could use in the lab.

#DeltaH_f^@, Br_2(l)# is defined as #0*kJ*mol^-1#. Data exist somewhere for calculation of #DeltaH_f^@, Br_2(g)#.
