A) absorbs \[\Delta \text{G}{}^\circ \]
B) produces ozone
C) eliminates moisture
D) absorbs \[C+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}Co\] and increases \[CO+\frac{1}{2}{{O}_{2}}\xrightarrow{{}}C{{O}_{2}}\] content
Correct Answer: D
Solution :
\[4K{{O}_{2}}+2C{{O}_{2}}\xrightarrow{{}}2{{K}_{2}}C{{O}_{3}}+3{{O}_{2}}\] Although \[\text{A=III,B=II}\] also reacts with moisture of the mbreath and does not completely eliminate it. \[4K{{O}_{2}}+2{{H}_{2}}O\xrightarrow{{}}4KOH+3{{O}_{2}}\]or \[4K{{O}_{2}}+4C{{O}_{2}}+2{{H}_{2}}O\xrightarrow{{}}4KHC{{O}_{3}}+3{{O}_{2}}\]
