The only way the book showed to do equilibrium is to do Keq = [A]^a [ B]^b / [C]^c
but that isnt even possible here. When I asked the teacher, he said I should be able to do this with some basic Algebra I. I am completely lost. Please help

 Consider the equilibrium

N2(g) + O2(g) + Br2(g) <===> 2 NOBr(g)

Calculate the equilibrium constant Kp for this reaction, given the following information (at 298 K):

2 NO(g) + Br2(g) <===> 2 NOBr(g) Kp = 0.49

2 NO(g) <===> N2(g) + O2(g) Kp = 2.1 x 1030

Note that [ B ] (without the spaces) is a formatting code for bold text, but that's a software issue.

Consider your first equilibrium, what is your expression for Keq, and then similarly with the partial equilibriums you list later?

are you sure there's enough information here to do this question?

Yes!

What's the expression for Kp for the reaction 2 NO(g) + Br₂(g)  2 NOBr(g) ?

Repeat for the other reactions, and see where that gets you.

LOL..I got it:) that's one funny question All you have to know is how to write the expressions for K_p
