Which has highest bond angle? `NO_(2), NO_(2)^(–) , NO_(2)^(+)`

The correct order of bond angle of NO_(2)^(+),NO_(2) and NO_(2)^(-) is

Arrange the following in order of decreasing N - O bond length NO_(2)^(-),NO_(2)^(-),NO_(3)^(-)

Arrange the following in the order of property indicated for each set: NO_(2), NO_(2)^(+), NO_(2)^(–) (decreasing bond angle)

The hybridisations of the atomic orbitals of nitrogen in NO_(2)^(-), NO_(2)^(+) and NH_(4)^(+) respectively are:

The reaction of nitrogen dioxide with carbon monoxide NO_(2)(g) +CO(g) rarr CO_(2)(g)+NO(g) has been studied and the following mechanism mechanism has been proposed: NO_(2)(g) + NO_(2)(g) rarr NO_(3)(g) +NO(g) " " (slow) NO_(3)(g) +CO(g) rarr NO_(2)(g)+CO_(2)(g)" " (fast) What rate law corresponding to this mechanism?
