Answer #1

we have

2NO​   ---------------->        N2 + O2 ​​ ​Kc=2.4X10^30

NO    + ½ Br2        ----------->        NOBr ​​ Kc=1.4

therefore

½ N2     +      ½ O2 + ½ Br2    ------------> NOBr ​

Kc net = [NOBr] / [N2]1/2 [O2]1/2 [Br2]1/2

            = 1.4 / 2.4X10^30

            = 9.04 X 10^-16
