Step 1

Any chemical reaction is said to be in equilibrium when the rate of the forward reactions becomes equal to the rate of backward reaction or when the concentration of the products and reactants becomes constant.

Suppose for a given reversible reaction in equilibrium:

Step 2

We need to find the equilibrium constant at constant concentration, then it can be calculated using the following expression:-

Where Kc is the equilibrium constant at constant concentration .C and D are products having stoichiometric coefficients c and d respectively whereas A and B are the reactants having stoichiometric coefficients a and b respectively.

Step 3

For the same reaction as below if written in re...
