B: How about your day off, Tony? A: It was terrible ! I studied very hard for my math   test l某温度下，在体积为5 L的密闭容器中，充入1molA气体，发生如下可逆反应： 2A（g）B(g)+C(g)；ΔH＝+akJ·mol－1 (a>0)，2min后反应达到平衡，A为0.4 mol。下列叙述中不正确的是A.充分反应后，反应吸收的热量为0.5a kJB.0-2 min时间内B物质的平均反应速率为0.03 mol/(L·min)C.达平衡后，保持温度和容器体积不变，再充入1 mol A，平衡向正反应方向移动D.若温度和容器体积不变，起始时充入B和C各0.5 mol，则达平衡时，n(A)等于0.4 mol
