| (I) slow decomposition of \[K{{O}_{2}}\] |
| (II) reaction of \[K{{O}_{2}}\] with \[C{{O}_{2}}\] in the exhaled air |
| (III) reaction of \[K{{O}_{2}}\] with moisture in the essential air |
| (IV) fast decomposition of \[K{{O}_{2}}\] |
A) I, II
B) II, III
C) I, III
D) II, IV
Correct Answer: B
Solution :
[b] \[2K{{O}_{2}}+C{{O}_{2}}\xrightarrow{{}}{{K}_{2}}C{{O}_{3}}+\frac{3}{2}{{O}_{2}}\] \[2K{{O}_{2}}+2{{H}_{2}}O\xrightarrow{{}}2KOH+{{H}_{2}}{{O}_{2}}+{{O}_{2}}\]
