| I understand that the change in free energy is zero when a system is at equilibrium, but I'm curious what happens to the change in enthalpy and entropy when equilibrium is reached. |

| I may be wrong but since enthalpy is heat, the change of heat at equilibrium would depend upon whether the reaction was endothermic or exothermic. Additionally, since all reactions are attempting to reach entropy of zero then a reaction at equilibrium would be rather close to a value of zero. That is how I am explaining my reasoning. |

The equilibrium state of a system maximizes the entropy because we have lost all information about the initial conditions except for the conserved variables; maximizing the entropy maximizes our ignorance about the details of the system.
Same is true for the enthalpy change... |
