`2CO(g) + O_(2)(g) to 2CO_(2)(g) , 2NO(g) + O_(2)(g) to 2NO_(2)(g)` . Which is relatively faster ? Why ?

Explanation

`2NO_((g))+O_(2(g)) to 2NO_((g))` is relatively faster. In both the reactions, the stoichiometry is same and number of bonds transformed is also same. The number of electrons shared in CO molecule is `6` and in NO molecule is `5`. Breaking bond in NO molecule is relatively easy than that in CO molecule. Further NO has unpaired electron and thus more reactive.
