Among the following process, which one does not produce energy?
A. NO2- -> NO3-
B. NH4+ -> NO2-
C. S0 -> SO42-
D. H2S -> S0
E. N2 -> NH4+
Homework Answers
Answer : Option (E) N2 -------> NH4+
Explanation :
The conversion of nitrogen gas to ammonium is a step involved in nitrogen fixation. This reaction requires input of energy,enzymes, etc. It does not produce energy.

In some aquatic ecosystems, nitrate (NO3–)
is converted to nitrite (NO2–), which then
decomposes to nitrogen and water. As an example of this second
reaction, consider the decomposition of ammonium nitrite:
$$NH4NO2(aq)N2(g)+2H2O(l)
3rd attempt
See Hint
See Periodic Table
What would be the change in pressure in a sealed 10.0 L vessel
due to the formation of N2gas when the ammonium nitrite
in 2.60 L of 0.800 M NH4NO2 decomposes at
25.0°C?
