Question

What are the characteristics of chemical equilibrium?

Accepted Answer

These are some characteristics of chemical equilibrium:

The chemical reaction should be reversible.

The equilibrium can be attained only if the system is closed, i.e. the reaction should be carried out in a closed vessel.

The opposing processes (i.e. forward and backward reactions) occur at the same rate and there is a dynamic but stable condition.

The observable properties of the system such as concentration, pressure, colour, etc. becomes constant at equilibrium and remains unchanged thereafter.

By bringing a change in conditions such as temperature, pressure or concentration, the equilibrium point can be shifted to the right or left-hand side as required. Thus, the reaction can be controlled to get more yield of products.

The equilibrium can be approached from either direction.

A catalyst does not alter the equilibrium point. It only increases the rate of reaction. The equilibrium is attained however.
