Question

How would you calculate `DeltaH^@` for the following reaction: `Br_2(g) -> Br_2(l)`?

Answer 1

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)`.
