The contribution of motion to themolar internal energy of benzene vapor at 100 ° C has to be estimated. Concept Introduction: The energy of a molecule due to its motion in the three dimensional space is referred to as the translational energy. The energy of a molecule due to its rotational motion in the three dimensional space is referred to as the rotational energy. The total molar internal energy of a molecule at temperature T is the sum of the contribution of translational and rotational kinetic energy.
