A thermodynamic equilibrium represents the state when all the three equilibrium (i.e., chemical, thermal and mechanical equilibrium) are attained at a time.
If true enter 1, else enter 0.
If true enter 1, else enter 0.
The word equilibrium means a state of balance. In an equilibrium state, there are no unbalanced potentials (or driving forces) with the system. A system that is in equilibrium experiences no changes when it is isolated from its surroundings.
A system in thermodynamic equilibrium satisfies:
1. Mechanical equilibrium (no unbalanced forces): Two systems are said to be in thermal equilibrium if their temperatures are the same.
2. Thermal equilibrium (no temperature differences): Two systems are said to be in mechanical equilibrium if their pressures are the same.
3. Chemical equilibrium: Chemical equilibrium is the state in which the chemical activities or concentrations of the reactants and products have no net change over time. Two systems are said to be in diffusive equilibrium if their chemical potentials are the same.
Hence, it is a true statement.
