CONCEPT:

Equilibrium in Physical Processes

• An equilibrium involving physical processes is a state where the opposing processes (such as evaporation and condensation, or freezing and melting) occur at the same rate.
• For equilibrium to be established, the system must be closed so that no matter can enter or leave the system.
• At equilibrium, all measurable properties (such as pressure, temperature, and concentration) remain constant over time.
• The equilibrium state is dynamic, meaning that the physical processes continue to occur, but their effects cancel each other out, resulting in no net change.

EXPLANATION:

• The statement that does not describe a general characteristic of equilibria involving physical processes is:

  Option 3: All the physical processes stop at equilibrium.

• This is incorrect because, at equilibrium, the physical processes do not stop; rather, they continue to occur at equal rates in both directions, maintaining a dynamic but stable condition.
• Hence, the correct answer is Option 3.

Therefore, Option 3 is not a general characteristic of equilibria involving physical processes.
