Creation of uncompensated heat

In an advancing irreversible process such as a mechanical movement of a body, dissipation of energy for instance from a mechanical form to a thermal form (frictional heat) takes place. The second law of thermodynamics defines the energy dissipation due to irreversible processes in terms of the creation of entropy Slrr or the creation of uncompensated heat Qirr. 

This equation 3.10 defines the creation of uncompensated heat Qlrr and the creation of entropy Sirr ... 

According to irreversible thermodynamics [Ref. 2.], the rate of the creation of uncompensated heat, which equals the rate of the creation of entropy times the absolute temperature, is equivalent to the driving force A times the rate v = d /dt of the irreversible reaction as shown in Eq. 3.14 (vid. Eq. 3.39) ...
