The rate of the forward reaction equals the rate of the reverse reaction.
<h3>What is dynamic equilibrium?</h3>
When it comes to chemical reactions, a dynamic equilibrium is a condition in which a reversible reaction produces products and reactants at an equal rate.
Dynamic equilibrium can only be achieved in a closed system. That is, a system in which there are no external influences in form of energy, material, or pressure.
For example, consider the following reversible reaction:
If the reaction is in dynamic equilibrium, there will not be a net production of reactants and products. In other words, the rate of production of A and B will be the same as the rate of production of C and D.
This is as opposed to static equilibrium in which the production of both reactants and products stops completely after reaching equilibrium.

Answer:
It is always twice the value of the actual yield.
Explanation:
Hygroscopic nature of NaOH is the main reason for the lower concentration of the sodium hydroxide in the solution.
<u>Explanation:</u>
- It is a well known fact that Sodium hydroxide pellets are hygroscopic in nature, which clearly means that the sodium hydroxide pellets absorbs moisture from the air, so that it becomes deliquescent.
- When the NaOH crystals are weighed, the crystals absorb moisture from the surroundings, and so the weight of the crystals may change, so the concentration of the solution was lower than the required one.So it is not possible to prepare NaOH solution under normal room temperature.
- So, while preparing the solution of NaOH we have to be more careful.
Answer:
No
Explanation:
it will not be a irreversible change because u can give back the pen if it is in its original state and the shop keeper might accept it back that is what mostly happens. if the pen breaks or is used then it might me called a irreversible change until then it is reversible if not used yet.
thank u
