【单选题】
在一定温度下，固定体积为2 L密闭容器中，发生反应：2SO 2 （g）＋O 2 （g） 2SO 3 （g）　ΔH<0，n（SO 2 ）随时间的变化如表： 时间/min 0 1 2 3 4 5 n（SO 2 ）/mol 0.20 0.16 0.13 0.11 0.08 0.08 则下列说法正确的是（　　）
A.
当v（SO 2 ）＝v（SO 3 ）时，说明该反应已达到平衡状态
B.
用O 2 表示0～4 min内该反应的平均速率为0.005 mol/（L·min）
C.
若升高温度，则SO 2 的反应速率会变大，平衡常数K值会增大
D.
再通入O 2 ，平衡右移，O 2 转化率减小，SO 2 转化率增大
