A students Activity: Take two 100ml of equilibrium marked as 1 and 2 and two glass tubes each of 30cm length. Fill half of the measuring cylinder-1 with coloured water and keep second cylinder empty.Put one tube in cylinder-1 and second tube in cylinder-2. Immerse one tube in cylinder-1, close its upper tip with a finger and transfer the coloured water contained in its lower portion to cylinder-2. Using second tube kept in 2nd cylinder transfer the coloured water in a similar manner from cylinder-2 to cylinder-1, in this way keep on transferring coloured water using the two glass tubes from cylinder-1 to 2 and from 2 to 1 till you notice that the level of coloured water in both cylinders becomes constant.

If you continue inter transferring colored solution between the cylinders, there will not be any further change in the levels of colored water in two cylinders. This indicates dynamic nature of equilibrium. Law of chemicals equilibrium and Equilibrium constant: At a given temperature, the product of concentration of the reaction products raised to the respective to the stoichiometric coefficients in the balanced chemical equation divided by the product of concentrations of reactants raised to their individual stoichiometric coefficients has a constants value. This is known as the ‘law of chemical equilibrium’.
