(a) What is the value of K_p for this reaction?

(b) What is the value of the equilibrium constant K_c for ${\text{2NH}}_{\text{3}}\left(g\right)\rightleftarrows {\text{N}}_{\text{2}}\left(g\right)+{\text{3H}}_{\text{2}}\left(g\right)?$

(c) What is K_c for ${\text{N}}_{\text{2}}\left(g\right)+{\text{H}}_{\text{2}}\left(g\right)\rightleftarrows {\text{NH}}_{\text{3}}\left(g\right)?$

(d) What are the values of K_p for the reactions described in parts (b) and (c)?
