After the reaction N 2 (g) + 3H 2 (g) 2 NH 3 (g) is run,

Question:

After the reaction N2(g) + 3H2(g) ⇆ 2 NH3(g) is run, an equilibrium mixture at 300 °C is 0.25 M in N2(g), 0.15 M in H2(g), and 0.090 M in NH3(g).

(a) What is the value of Keq?

(b) Which way does the equilibrium shift when H2(g) is added?

(c) What happens to the value of Keq when H2(g) is added?

(d) Suppose we write this reaction as:

2N(g) + 6 H(g)  4NH3(8)

Now what is the value of Keq?

(e) The equilibrium shifts to the right when the reaction mixture is cooled. Is this reaction exothermic or endothermic? Justify your choice.
