Question

Write the correct equilibrium expression for the following reversible equation: (2 pts)

Answer 1

Answer:

The answer to your question is below

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 = $\frac{C^{c} D^{d}}{A^{a} B^{b}}$

For the reaction given,

              Kc = $\frac{[N_{2}][O_{2}]}{[NO]^{2}}$

Answer 2

Answer:

Kc = [N2]*[O2] / [NO]²

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
