The equilibrium constant
Using the table approach, the equilibrium concentrations of the reactants and the products can be found.
The equilibrium concentration values are then substituted into the equilibrium expression to get the change in the amount, x.
On rearranging we get a quadratic equation.
On solving the quadratic equation the value of x obtained.
On solving we get two values for x, the positive value for x is taken.
Hence,
The equilibrium composition of the given mixture was found by using the value of equilibrium constant and initial amount of the reactants.
