Equilibrium Question

Question

At a given temperature, K = 2.4×10⁴ for the following forward reaction:

2NO(g)+O2(g) -----> 2NO2(g)

1.Write the reverse reaction. Be sure to include all states of matter.

2.What is the K value for the reaction above written in the reverse direction?

Answer 1

1). 2NO₂(g) ==> 2NO(g) + O_÷2(g)

2). K = 1 ÷ 2.4x104 = 4.2x1^0-5
