What is △ H for the formation of ozone?
The enthalpy of formation of ozone is 142.7 kJ / mol.
Is Br2 L → Br2 G exothermic?
The Attempt at a Solution
The chemical reaction is going from liquid to gas, therefore the entropy is increasing because the reaction is causing more macrostates due to the greater area of distribution for the gas molecules. The reaction is exothermic, because its giving off heat.

How do I find molar mass?
The characteristic molar mass of an element is simply the atomic mass in g/mol. However, molar mass can also be calculated by multiplying the atomic mass in amu by the molar mass constant (1 g/mol). To calculate the molar mass of a compound with multiple atoms, sum all the atomic mass of the constituent atoms.

Why Br2 is a liquid?
Bromine is a liquid because the intermolecular forces are strong enough so that it does not evaporate. Bromine forms diatomic molecules and Van der Waals interactions are sufficiently strong. … The mass of bromine in the oceans is about one three-hundredth that of chlorine.
