问题

选项 A、4?mol?A+2?mol?B B、2?tool?A+1?mol?B+3?tool?C+l?mol?D C、3?mol?C+1?tool?D+1?tool?B D、3?mol?C+I?mol?D

答案 D

解析本题考查化学平衡中的等效平衡。A项相当于增大压强，达到平衡时C的浓度大于amoL／L。B项与A项是等效平衡．达到平衡时C的浓度大于amol／L．C项相当于2m01A+2molB．达到平衡时C的浓度大于amol／L。D项与题干所给条件是等效平衡．达到平衡时C的浓度等于Aamol／L。故本题选D。

错误信息

消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
