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.

neutrons are in the middle of the atom and the electrons, which are much smaller.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
