4) C
5) E
6) D
7) Kc = .0634 8a) decrease: consume NH3 shifts equilibrium to the left
8b) increase, increase in T shifts reaction in endothermic direction
8c) increase, increased volume (decreased pressure) shifts reaction to make more moles of gas
8d) remain the same, adding an inert gas increases the total pressure of the system but it doesn't change the partial pressure of any of the reactants (or the value of the equilibrium constant) and therefore would not cause a shift in equilibrium.
8e) increase, the reaction will shift to the left in coming to equilibrium, but at equilibrium you will still have more ammonia than you started with.
9a) K = .477
9b) no change, equal morels of gas on each side.
9c) decrease, a larger volume would make the gas more dilute.
10) [BrCl] = .668 M
11) [I2] = [Cl2] = 3.99 x 10-2 M [ICl] = .120 M
12) a) [CO2] = [H2]= 6.67 x 10-2 M [CO] = [H2O]= 3.33 x 10-2 M
b) [CO2] = [H2]= 5.33x 10-2 M [CO] = [H2O]= 2.67 x 10-2 M
13) [NO] = [SO3]= 6.76x 10-2 M [SO2] = [NO2]= 7.38 x 10-3 M
14) [PCl3] = [Cl2]=.1 M [PCl5]= .2 M
15) a) Kc = .72
b) [CO2] = [H2]= 1.47x 10-2 M [CO] = [H2O]= 1.73 x 10-2 M

Do all post-lab calculations and the post-lab questions. The post-lab questions are on Pg. 15, which you have. The post-lab calculations are on Pgs. 11-14. You need to do calculations for Part 1 and Part 2 (a,b,c,d). We did not do part 3/4 of the experiment, so you will not do those calculations.
