The Gibbs-Duhem theory of stability of equilibrium states has been extended to determine the stability of irreversible processes. The basic concept of virtual displacement in the reverse direction on the real trajectory, which is involved in the celebrated Gibbs-Duhem theory, has been used. This establishes that all thermodynamically describable processes are thermodynamically stable. This outcome led us to reformulate the fourth law of thermodynamics. Moreover, our present investigations illustrate the basis of the universal inaccessibility principle formulated earlier by one of the present authors (AAB).
