                                  2NO +  Br2    2NOBr
Initial moles           0.087   0.043        0
 
 
At eq.                0.087-2x  0.043-x      2x
 
 
2x = 0.0518
x  = 0.026
 
 
Equilibrium conc of NO and Br2 are
 
NO===>0.087-2x = 0.035moles/l
Br2===>0.043-x = 0.017 moles/l
 
There is no better feeling in this world than being a winner!
