The equilibrium constant for the gas phase reaction n2 (g) + o2 (g) ⇌ 2no (g) is keq = 4.20 ⋅ 10-31 at 30 °c. at equilibrium, the equilibrium constant for the gas phase reaction n2 (g) + o2 (g) 2no (g) is keq = 4.20 10-31 at 30 °c. at equilibrium, products predominate reactants predominate roughly equal amounts of products and reactants are present only products are present only reactants are present

The equilibrium constant for the gas phase reaction N₂(g) + O₂(g) ⇌ 2NO(g) is Keq = 4.20x10⁻³¹ at 30 °C. At equilibrium, reactants predominate

Explanation:

For the equilibrium

N₂(g) + O₂(g) ⇌ 2NO(g); Keq = 4.20x10⁻³¹

The formula is:

Keq =

As keq = 4.20x10⁻³¹

4.20x10⁻³¹ =

As keq <<< 1 mathematically [NO]²<<< [N₂][O₂]

That means, reactants predominate.

I hope it helps!

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
