The vaporization of Br2 from the liquid to the gas state requires 7.4 kcal/mol. write a reaction showing heat as a product or reactant

Br₂(l) + ΔV → Br₂(g)

Explanation:

When a chemical or phase change occurs during a chemical process some heat is absorbed or released. For the process of vaporization of a substance, the heat (Usually required) is ΔV (How many energy is required for the process occurs).

In the vaporization of Br2 there are required 7.4kcal/mol, Δv. The reaction is:

i believe that it is a exoplanet

the answer would be b i believe
