Answer:

Kc = [N2]*[O2] / [NO]²

Step-by-step explanation:

Step 1: Data given

The balanced equation is 2NO (g) ⇌ N2 (g) + O2 (g)

Step 2: Define Kc

For the equation aA + bB ⇌ cC + dD

Kc =[ C^c] * ]D^d ]/ [A^a]*[B^b]

Step 3: Calculate Kc for this reaction

For the reaction 2NO (g) ⇌ N2 (g) + O2 (g)

Kc = [N2]*[O2] / [NO]²

Answer:

The answer to your question is below

Step-by-step explanation:

Balanced chemical reaction

2NO ⇔ N₂ + O₂

Chemical equilibrium is the phase or state in which the concentration of the products and the reactants do not change anymore.

General Formula

aA + bB ⇔ cC + dD

Kc =
(C^(c) D^(d))/(A^(a) B^(b))

For the reaction given,

Kc =
([N_(2)][O_(2)])/([NO]^(2))
