Chapter 12, Problem 12.92PAE

Consider the following system:

   $4{\text{NH}}_3\left(g\right)+3{\text{O}}_2\left(g\right)\rightleftarrows 2{\text{N}}_{\text{2}}\left(g\right)+6{\text{H}}_{\text{2}}\text{O}\left(\mathcal{l}\right)△H°=-153.04\text{kJ}$

(a) How will the amount of ammonia at equilibrium be affected by

(1) removing ${\text{O}}_2\left(g\right)$ ?

(2) adding N2(g)?

(3) adding water ${\text{N}}_{\text{2}}\left(g\right)$ ?

(4) expanding the container at constant pressure?

(5) increasing the temperature?

(b) Which of the above factors will increase the value of K? Which will decrease it?
