Question

Identify the common property for a chemical reaction at dynamic equilibrium.

• A. The measurable properties like concentration, density, colour, pressure, etc., remain constant at constant temperature.
• B. The forward and backward reactions take place with the same rate.
• C. It can be achieved from both directions.
• D. All of the above.

Answer 1

The correct option is D

All of the above.

Dynamic Equilibrium: Under a particular set of conditions, the state in which the quantifiable parameters of the system, such as concentration, pressure, density, and colour, do not change significantly over time.

The explanation for the Correct option: (D)

A characteristic of a chemical process in dynamic equilibrium:

1. At a fixed temperature, observable attributes such as density, colour, pressure, concentration, and so on stay constant.
2. It is possible to achieve equilibrium in any way.
3. Only in a closed system can equilibrium be achieved. This stops the reaction's products from escaping.
4. The use of the catalyst has no effect on the equilibrium position.
5. Unless external causes disrupt the equilibrium state, it continues to exist.

The explanation for incorrect option:

(A) This option is incorrect since not only is this statement right, but also all of the other statements are correct.

(B) This option is incorrect since not only is this statement right, but also all of the other statements are correct.

(C) This option is incorrect since not only is this statement right, but also all of the other statements are correct.

Conclusion: Hence, option (D) is correct.
