A possible mechanism for the overall reaction
Br2 (g) + 2NO (g) -> 2NOBr (g)
NO (g) +Br2 (g) (equilibrium arrows: on top it says k1 and on bottom k-1) NOBr2 (g) (fast) step 1
NOBr2 (g) + NO (g) ->(on top of arrow k2) 2NOBr (slow) step 2
the question: which of the following the reaction intermediate?
