Explanation:
2NH3(g) --> 3H2(g) + N2(g)
The equlibrium constant is the ratio of the concentration of products to that of reactants.
Keq = [Products] / [Reactants]
So to write the expression, we have to identify our reactants and products.
Reactants = NH3
Products = H2 and N2
The coefficients are expressed as powers of the entities in the expression, this leads us to;
[Products] = [H2]² [ N2]
[Reactants] = [NH3]³
Keq = [NH3]³ / [H2]² [ N2]
Answer:
Pure solids and pure liquids are not included in the equilibrium constant expression.
Since all reactants and products are gases, they are all included in the equilibrium constant expression.
Write the concentrations of the products in the numerator (top) and the reactants in the denominator of the fraction.
Raise the concentrations to the correct power, based on the coefficients.
Write the expression as
