40. Solving a chemistry problem

68. From the following values of thermodynamic functions, indicate those that are a criterion for the state of equilibrium in an isolated system (P, T \u003d const):
a) ΔH < 0, b) ΔG < 0, c) ΔS > 0, d) ΔG = 0, e) ΔS = 0
Give a reasoned answer. Is it possible to spontaneously change the physical quantity in the criterion you have chosen after the equilibrium has been established? If not, then how to achieve a change in the physical quantity in the criterion you have chosen with the help of an external influence?
