Use the following information to answer questions, assuming the same temperature for all questions.(假设所有问题的温度相同,根据以下信息回答问题。) 3 H 2 (g) + N 2 (g) ⇋ 2 NH 3 (g), K c = 60 If the reaction quotient for the above reaction were Q c = 73, then we can accurately predict that the following concentration changes must take place for the reaction to reach equilibrium. (如果上述反应的反应Qc = 73,那么我们可以准确地预测对于反应达到平衡不同物质的浓度变化。)
A.
H 2 , N 2 increase; NH 3 decrease(H 2 和N 2 的浓度增加,NH 3 的浓度减小。)
B.
H 2 , N 2 decrease; NH 3 increase(H 2 和N 2 的浓度减小,NH 3 的浓度增加。)
C.
H 2 , NH 3 decrease; N 2 increase(H 2 和NH 3 的浓度减小,N 2 的浓度增加。)
D.
all concentrations increase(所有物质浓度都升高)
E.
all concentrations decrease(所有物质浓度都降低)
