336759 Reaction carried out by \(\mathrm{N}_{2}\) fixing microbes include
I. \(2 \mathrm{NH}_{3}+3 \mathrm{O}_{2} \rightarrow+2 \mathrm{NO}_{2}^{-}+2 \mathrm{H}^{+}+2 \mathrm{H}_{2} \mathrm{O}\)
II. \(2 \mathrm{NO}_{2}^{-}+\mathrm{O}_{2} \rightarrow 2 \mathrm{NO}_{3}\)
Which of the following statements about these equations is not true
