在密闭容器中,发生以下反应:3A(g) + B(g)  xC(g) 现有甲、乙两个容

在密闭容器中,发生以下反应:3A(g) + B(g)  xC(g)

现有甲、乙两个容积相等的恒容密闭容器,向甲中通入6 mol A2 mol B,向乙中通入1.5 molA0.5 mol B3 mol C,控制温度不变,使上述反应达到平衡,此时测得甲、乙两容器中C的体积分数都为0.2

 (1)若平衡时,甲、乙两容器中A的物质的量相等,则x ______;若平衡时甲、乙两容器中A的物质的量不相等,则x ______

 (2)平衡时,甲、乙两容器中AB的物质的量之比是否相等______(填相等不相等),平衡时甲中A的体积分数为______

答案

1  2   4  2)相等   0.6
