For the reaction $H_{2(g)} + I_{2(g)} \rightleftharpoons 2HI_{(g)}$,the equilibrium constant changes with:

In a chemical reaction,equilibrium is established when:

Write the general characteristics of equilibria involving physical processes.

$A$ liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased.
$(a)$ What is the initial effect of the change on vapour pressure?
$(b)$ How do rates of evaporation and condensation change initially?
$(c)$ What happens when equilibrium is restored finally and what will be the final vapour pressure?

Explain equilibrium in a saturated solution and its dynamic nature.

Equilibrium is a steady state,but it is dynamic in nature. What is the meaning of this statement?
