Calculate the equilibrium constant (K) for the ammonia synthesis reaction at

Question

25°C and show how K is related to the partial pressures of the species at
equilibrium. Consider that the overall pressure is low enough for the gases to be treated as perfect.

N2(g) + 3H2(g) -> 2NH2(g)

Answer 1

you can work out K, but notice the concentraton of the species in the term: concentration is n/V which is equal to P/RT

so concentration is directly a function of Pressure.
