Answer:
2NO + Br2 <==> 2NOBr
Step-by-step explanation:
From the question given, the equilibrium expression for the chemical reaction is
Keq = [NOBr]^2/ [NO]^2 [Br2]
The Equilibrium constant is simply defined as the ratio of the concentration of the products raised to their coefficient to that of the concentration of the reactants raised to their coefficient.
From the equilibrium expression given above, the following were obtained:
Products => NOBr
Reactants = NO and Br2
The equation for the reaction is given as:
NO + Br2 <==> NOBr
Putting their coefficients, we have:
2NO + Br2 <==> 2NOBr
Therefore, the reaction is:
2NO + Br2 <==> 2NOBr
