Question 1
0.75 mol of N
2 and 1.20 mol of H
2 are placed in a 3.0 liter container. When the reaction
N
2(g) + 3 H
2(g)

2 NH
3(g) reaches equilibrium, [H
2] = 0.100 M. Which of the following is true?
◦ [NH
3] = 0.150 M
◦ [NH
3] = 0.200 M
◦ [N
2] = 0.650 M
◦ [N
2] = 0.250 M
◦ [NH
3] = [H
2] = 0.05 M
Question 2
2.5 moles H
2O and 100 g of C are placed in a 50-L container. At equilibrium for the reaction C(s) + H
2O(g)

CO(g) + H
2(g), [H
2] = 0.040 M. Which of the following is true?
◦ [CO] = 0.020 M
◦ [H
2O] = 0.010 M
◦ no carbon is left
◦ [H
2O] = 0.020 M
◦ [C(s)] = 0.04 M
