Horses help us achieve many of our aims.Girls can learn to develop responsibility,self-confidence and personal connections in their lives while having fun.Using horses as a wonderful tool for education,our camps offer an interesting place fo13．在一定温度下，向2L恒容密闭容器中充入1mol A，发生A（g）?B（g）+C（g）反应．反应过程中c（C） 随时间变化的曲线如图所示，下列说法不正确的是（　　）A．反应在0～50s的平均速率v（C）=1.6×10-3mol/（L•s）B．该温度下，反应的平衡常数K=0.025C．保持其他条件不变，升高温度，平衡时c（B）=0.11mol/L，则该反应的△H＜0D．反应达平衡后，再向容器中充入 1 mol A，该温度下再达到平衡时0.1mol/L＜c（C）＜0.2mol/L
