Hess’s law deals with:

Which type of molecular motion does contribute towards internal energy for an ideal mono-atomic gas? 

The total heat content of a system is

$$\Delta H_{f}=$$ -98.2 K.Cal/mole
$$S_{Na} =$$ 36 K.Cal/mole
$$I_{Na} =$$ 118.5 K.Cal/mole
$$\dfrac{1}{2}D_{Cl_{2}}=$$ 29 K.Cal/mole
$$U_{NaCl}=$$ -184.2 K.Cal/mole
From the data given below for $$NaCl$$, the electron affinity of chlorine $$[-E_{a}]$$ is:
