Question
  1. Express the equilibrium constant for this reaction:   N2(g) + 3 H2(g) <=>  2 NH3(g)

       

    K = [NH3]2 / ([NH3]2 x [N2])

       

    K = ([NH3]2 x [N2]) / [H2]3

       

    K =  ([N2] x [H2]3) / [NH3]2

Expert Solution
Step 1

Equilibrium constant of any reaction can be written in terms of concentration of reactants and products.

The concentration terms of products appear in the numerator and the concentration terms of products appear in the denominator.

And the reaction coefficients of a particular specie in the reaction is the power of concentration term of that specie in the equilibrium constant expression.
