The numerical value of the equilibrium constant, Kc, for the following gas phase reaction is 0.50 at a certain temperature. When a certain reaction mixture reaches equilibrium, the concentration of O2 is found to be 2.0 M, while the concentration of SO3 is found to be 10 M. What is the equilibrium concentration of SO2 in this mixture

10 M

Explanation:

The Balanced Reaction is;

2SO2 + O2 <> 2SO3

As Equilibrium Concentration of O2 is given to be;

[O2] = 2.0 M

And the Equilibrium Concentration of SO3 is given to be

[SO3] = 10 M

With the Equilibrium Constant as;

Kc = 0.50

Then we can solve for the concentration of SO2 as,

Kc = [SO3]2 / ( [SO2]2 × [O2] )

0.50 = (10)2 / ( [SO2]2 × 2.0 )

0.50( [SO2]2 × 2.0 )

[SO2]2 = 100

Solving for SO2 we get,

[SO2] = (100)1/2 = 10 M

Therefore, the Equilibrium Concentration of SO2 in the mixture is 10 M

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
