1. For the following reversible reaction, 
 
3 H2 (g) + 1 N2 (g) <==> 2 NH3 (g) + Energy 
 
 
a) Write the Equilibrium constant expression for this reversible reaction. 
 
 
 
 
b) For the reversible reaction above, I found that I have the following equilibrium concentrations, what is Equilibrium constant ( K ) and its units. 
[H2 (g)]E = 0.431M, [N2 (g)]E = 0.673M, and [NH3 (g)]E = 2.91M, 
 
 
 
 
 
c) Simply state next to each of the following stresses on the above equilibrium system, if the equilibrium will 1) shift to the Right, 2)shift to the Left, or 3) No shift in equilibrium 
 
Adding a compound that will consume N2 (g) 
 
 
d) Filling in the following <nowiki>LeChatlier's Principle</nowiki> table for: 
 
Stress: Decrease Temperature (___________________) 
 
How rxn tries to remove stress: _________________________________________________ 
 
Circle: Make more product or more reactant (fill in for pressure changes)__________________ 
 
Circle: Favoring: Forward rxn or Backward rxn: (fill in for temperature changes) _____________ 
 
Circle: Shift Equilibrium to: Left(more reactant) or Right (more product) 
 
e) If the above reversible reaction did not have the Equilibrium constant you calculated in Question 1b, but instead had a value of K = 1000. That would indicate that you have MORE PRODUCT or MORE REACTANT in your Equilibrium system. Circle the appropriate answer. 
 
 
2. Do you need the reactants to have the same concentration of reactants as the products to be at Equilibrium. Yes or No (Circle Correct answer).
 
 
3. Explain what Dynamic Equilibrium means.
