Aliter of the gas mixture at equilibrium contains 0.0045 mol of n2o4 and 0.030 mol of no2 at 10c. write the expression for the equilibrium constant (keq) and calculate the value of the constant for the reaction.

Keq = [NO₂]²/[N₂O₄] = 0.2.

Explanation:

N₂O₄ ⇄ 2NO₂

The expression of the equilibrium constant (Keq):

Keq = [NO₂]²/[N₂O₄]

∴ Keq = [NO₂]²/[N₂O₄] = (0.03)²/(0.0045) = 0.2.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
