题目.某恒温密闭容器中,可逆反应A(s)B(?)+C(g)△H=-Q kJ/mol达到平衡。缩小容器体积,重新达到平衡时,C(g)的浓度与缩小体积前的平衡浓度相等。以下分析正确的是()。A.产物B的状态只能为固态或液态B.平衡时,单位时间内n(A)_(消耗):n(C)_(清耗)=1:1C.保持体积不变,向平衡体系中加入B,平衡可能向逆反应方向移动 Title: A constant temperature closed vessel, reversible reaction A (s)  B (?) + C (g) △ H = -Q kJ / mol balance. Reduce the volume of the container, and when equilibrium is reached again, the concentration of C (g) equals the equilibrium concentration before volume reduction. The following analysis is correct (). A. The state of product B can only be solid or liquid B. At equilibrium, n (A) _ (consumption): n (C) _ (depletion) = 1: 1C per unit time. Keeping the volume constant, By adding B into the system, the equilibrium may move toward the reverse reaction
