Question

Which of the following is not a general characteristic of equilibria involving physical processes?

विकल्प

• (i) Equilibrium is possible only in a closed system at a given temperature.

• (ii) All measurable properties of the system remain constant.

• (iii) All the physical processes stop at equilibrium.

• (iv) The opposing processes occur at the same rate and there is dynamic but stable condition.

Answer 1

(iii) All the physical processes stop at equilibrium.

Explanation:

A physical equilibrium is having dynamic nature, both forward and reverse process occur at equal rates. Some kind of motion is always present. The individual molecules continuously move from one phase to another.
