A liquid is in equilibrium with its vapor in a closed vessel at a fixed temperature. The vessel is connected by a stopcock to an evacuated vessel. When the stopcock is opened, will the final pressure of the vapor be different from the initial value if (a) some liquid remains;

Respuesta :

Since there are the same number of molecules in the liquid and vapour phases in this situation, the end pressure would be the same as the initial pressure at equilibrium, before the stopcock was opened.

What is equilibrium, exactly ?

When a reversible chemical reaction is occurring, chemical equilibrium is the state in which there is no net change in the number of reactants or products. In a reversible chemical reaction, the products start interacting with the initial reactants as soon as they are created.

  • We might be able to pinpoint the equilibrium's location using the equilibrium constant. The closer the equilibrium is to the products, the higher the equilibrium constant.
