Question

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

• A. Equilibrium is possible only in a closed system at a given temperature.
• B. The equilibrium is dynamic in nature.
• C. Measurable properties of the system keep changing.
• D. Equilibrium can be attained from both sides of the reaction.

Answer 1

The correct option is C Measurable properties of the system keep changing.

Measurable properties state variables are Pressure, temperature, the volume is constant at equilibrium. If one of these properties change, the system changes to a new state. Macroscopic properties of a system depend on these state variables.
