Questions:
1. Calculate the value of [N2leq if [H2leq = 2.0 M, [NH3leq = 0.5 M, and
Kc = 2.
N₂(g) + 3 H₂(g) = 2 NH3(g)
A) 62.5 M
B) 0.031 M
C) 0.062 M
D) 0.40 M
E) 0.016 M
2. Consider the following reaction:
COCl2(g) <--> CO(g) + Cl₂(g)
A reaction mixture initially contains 1.6 M COCI2. Determine the
equilibrium concentration of CO if Kc for the reaction at this temperature is
8.33 × 10-4. Calculate this based on the assumption that the answer is
negligible compared to 1.6.
A) 3.7 x 10-2 M
B) 1.5 x 10-3 M
C) 4.2 × 10-4 M
D) 2.1 x 10-2 M
E) 1.3 × 10-3 M
