Answer:
No, it is:
[tex]2NH_3\rightarrow N_2+3H_2[/tex]
Explanation:
Hello,
In this case, all the given equation could be simplified by a factor of two to yield:
[tex]\frac{4}{2} NH_3 \rightarrow \frac{2}{2} N_2+\frac{6}{2} H_2[/tex]
Therefore, the answer is no, so it the lowest one is:
[tex]2NH_3\rightarrow N_2+3H_2[/tex]
Regards.
