It is pressure exerted by vapours at:
Correct answer: C. Dynamic equilibrium
- A. Static equilibrium
- B. Dynamic equipment
- C. Dynamic equilibrium
- D. None
Explanation
A state in which the forward and reverse reactions of a chemical equation are happening at the same rate.The concentrations of the reactants and products do not change over time.The system is stable, but it is not static.The equilibrium can be disrupted by changes in temperature, pressure, or concentration. The vapour pressure of a liquid is a pressure exerted by the vapours of the liquid in dynamic equilibrium with the liquid at a given temperature.

About Evaporation, Boiling Point and Vapour Pressure
Evaporation is the escape of higher-energy molecules from a liquid surface, while vapour pressure is the pressure exerted by vapour in equilibrium with that liquid. The topic distinguishes evaporation from boiling and relates both to temperature, intermolecular forces, surface area, atmospheric pressure and the boiling point.
