Question
X2(g) + Y2(g) ⇌ 2 XY(g) Kc = 3.0
A mixture of X2(g) , Y2(g) , and XY(g) is placed in a previously evacuated, rigid container and allowed to reach equilibrium at a constant temperature, as shown above. Which of the following sets of initial concentrations would lead to the formation of more product as the system moves toward equilibrium?
A.✓ Correct
[X2]initial = 0.40 M, [Y2]initial = 0.40 M, [XY]initial = 0.20 M
B.
[X2]initial = 0.30 M, [Y2]initial = 0.30 M, [XY]initial = 0.90 M
C.
[X2]initial = 0.15 M, [Y2]initial = 0.15 M, [XY]initial = 0.30 M
D.
[X2]initial = 0.10 M, [Y2]initial = 0.10 M, [XY]initial = 0.20 M
