1．
一定温度下，在三个体积均为\(\rm{2.0 L}\)的恒容密闭容器中发生反应：\(\rm{PCl_{5}(g) \underset{}{\overset{}{⇌}} PCl_{3}(g)+Cl_{2}(g)}\)
编号 | 温度 \(\rm{(℃)}\) | 起始物质的量\(\rm{(mol)}\) | 平衡物质的量\(\rm{(mol)}\) | 达到平衡所需时间 \(\rm{(s)}\) |
\(\rm{PCl_{5}(g)}\) | \(\rm{PCl_{3}(g)}\) | \(\rm{Cl_{2}(g)}\) |
Ⅰ | \(\rm{320}\) | \(\rm{0.40}\) | \(\rm{0.10}\) | \(\rm{0.10}\) | \(\rm{t}\)\(\rm{{\,\!}_{1}}\) |
Ⅱ | \(\rm{320}\) | \(\rm{0.80}\) | | | \(\rm{t}\)\(\rm{{\,\!}_{2}}\) |
Ⅲ | \(\rm{410}\) | \(\rm{0.40}\) | \(\rm{0.15}\) | \(\rm{0.15}\) | \(\rm{t}\)\(\rm{{\,\!}_{3}}\) |
