Question

Which of the given options is not a general characteristic of equilibrium involving a physical process?

• A. Equilibrium is possible only in a closed system at a given temperature.
• B. The opposing processes occur at the same rate and there is a dynamic but stable condition.
• C. All the physical processes stop at equilibrium.
• D. All measurable properties of the system remain constant.

Answer 1

The correct option is C All the physical processes stop at equilibrium.

Characteristics of physical equilibrium:

• Measurable properties (T, P, V, etc.) of the system become constant.
• Dynamic in nature; i.e., both the forward and backward processes happen but at the same speed, making no change in total.
• Takes place in a closed system.
