通过以下反应可获得新型能源二甲醚\(\rm{(CH_{3}OCH_{3})}\)。下列说法不正确的是\(\rm{(}\) \(\rm{)}\)

\(\rm{①C(s)+H_{2}O(g)=CO(g)+H_{2}(g)ΔH_{1}=a kJ·mol^{-1}}\)

\(\rm{②CO(g)+H_{2}O(g)=CO_{2}(g)+H_{2}(g)ΔH_{2}=b kJ·mol^{-1}}\)

\(\rm{③CO_{2}(g)+3H_{2}(g)=CH_{3}OH(g)+H_{2}O(g)ΔH_{3}=c kJ·mol^{-1}}\)

\(\rm{④2CH_{3}OH(g)=CH_{3}OCH_{3}(g)+H_{2}O(g)ΔH_{4}=d kJ·mol^{-1}}\)

A．若反应\(\rm{①}\)为吸热反应，高温条件下反应\(\rm{①}\)能自发进行

B．反应\(\rm{③}\)也是\(\rm{CO_{2}}\)资源化利用的方法之一

C．反应\(\rm{C{{H}_{3}}OH(g)=\dfrac{1}{2}C{{H}_{3}}OC{{H}_{3}}(g)+\dfrac{1}{2}{{H}_{2}}O(g)}\)的\(\rm{\Delta H=\dfrac{d}{2}kJ\cdot mo{{l}^{-1}}}\)
