Consider the following reaction equation: (2NO_{(g)} + O_{{2}{(g)}} to 2NO_{{2}{(g)}}). What is the change in the oxidation number of nitrogen?
-
A.
+2 to 0 -
B.
+2 to -2 -
C.
+2 to +4 -
D.
+4 to +2
Correct Answer: Option C
Explanation
In NO, the oxidation number for nitrogen is N – 2 = 0
⇒ N = +2
In (NO_{2}), we have N – (2×2) =0
N – 4 =0
N =+4
