What is meant by chemical equilibrium?

Chemical equilibrium is a state in which the rate of evaporation is equal to the rate of condensation, resulting in a constant vapour pressure.

Describe the process of molecules in a closed container reaching equilibrium.

In a closed container, molecules with higher kinetic energy escape the liquid surface into the vapor phase, while an equal number of molecules from the vapor phase strike the liquid surface and return to the liquid phase, resulting in a constant vapor pressure and equilibrium.

What does the double arrow in the representation H2O(l) ⇌ H2O(vap) indicate?

The double arrow indicates that the process of evaporation and condensation is simultaneously occurring in both directions at equilibrium.

Explain the significance of the rate of evaporation being equal to the rate of condensation in chemical equilibrium.

<p>When the rate of evaporation is equal to the rate of condensation, it results in a constant vapor pressure and signifies that the system has reached equilibrium, with no net change in the amount of liquid and vapor.</p> Signup and view all the answers
