Chapter 15, Problem 106E

Consider the reaction:

   ${\text{N}}_{\text{2}}\left(\text{g}\right)+{\text{3H}}_{\text{2}}\left(\text{g}\right)\to {\text{2NH}}_{\text{3}}\left(\text{g}\right).$

a. Write the equilibrium constant expression for this reaction.
If some hydrogen is added, before the reaction shifts:
b. How will the numerator and denominator of the expression in part a compare to the value at equilibrium?
c. Will $▱$ be larger or smaller than K? Why?
d. Will the reaction have to shift forward or backward to retain equilibrium? Explain.
e. Are your answers for b—d consistent with Le Chátelier’s principle? Explain.
