Problem

One mechanism for the synthesis of ammonia proposes that N 2 and H2 molecules catalytically dissociate into atoms:
N2(g) ⥫⥬ 2N(g)       log K p = −43.10
H2(g) ⥫⥬ 2H(g)       log K p = −17.30

(a) Find the partial pressure of N in N2 at 1000. K and 200. atm.
(b) Find the partial pressure of H in H2 at 1000. K and 600. atm.
(c) How many N atoms and H atoms are present per liter?

(d) Based on these answers, which of the following is a more reasonable step to continue the mechanism after the catalytic dissociation? Explain.
                        N(g) + H(g) ⟶ NH(g)
                   N  2(g) + H(g) ⟶ NH(g) + N(g)
