Describe how to write the Keq expression for the following reaction. 2NH3(g) 3H2(g) + N2(g)

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]

particle   p is an electron and particle q is a neutron
