The equilibrium expression for a chemical reaction is Keq = [NOBr]2/[NO]2[Br2]. What is the reaction?

2NO 2NOBr + Br2

2NO + Br2 2NOBr

Br2 2NO + 2NOBr

2NOBr 2NO + Br2

what do u think is the reaction?

somy · Answer

think of the earlier questions and about the formula

anonymous · Answer

i think it is C thats what i chose anyways is that correct

somy · Answer

Kc= product/ reactant 
power is coefficient of the compound
now which reaction is matching?

somy · Answer

No

anonymous · Answer

SO it B

anonymous · Answer

its*

somy · Answer

bingo!! :)

somy · Answer

thats why u should look carefully, don't jump up to the one that looks correct to u at first sight, first look, analyze then check what the question is asking for :)

alphadxg · Answer

the correct answer would be 

2NO + Br2 ↔ 2NOBr

Your answers are not clear.
