1．
一定温度下，在三个体积均为\(\rm{1.0 L}\)的恒容密闭容器中发生反应：\(\rm{2CH_{3}OH(g)\overset{}{⇌} CH_{3}OCH_{3}(g)+H_{2}O(g)}\)
容器 编号 | 温度\(\rm{/℃}\) | 起始物质的量\(\rm{/mol}\) | 平衡物质的量\(\rm{/mol}\) |
\(\rm{CH_{3}OH(g)}\) | \(\rm{CH_{3}OCH_{3}(g)}\) | \(\rm{H_{2}O(g)}\) |
Ⅰ | \(\rm{387}\) | \(\rm{0.20}\) | \(\rm{0.080}\) | \(\rm{0.080}\) |
Ⅱ | \(\rm{387}\) | \(\rm{0.40}\) | | |
Ⅲ | \(\rm{207}\) | \(\rm{0.20}\) | \(\rm{0.090}\) | \(\rm{0.090}\) |
下列说法正确的是 \(\rm{(}\) \(\rm{)}\)
