Question

The vaporization of Br2 from the liquid gas to the solid state requires 7.4 kcal/nil what is the triangleH for this process

Answer 1

The initial state of the compound Br2 is liquid. The final state is then solid. We know for certain that the liquid state has higher energy as compared to solid state. Due to this fact, Br2 must release energy to be in solid form. Therefore, the change in enthalpy is:

ΔH = -7.4 kcal/nil
