At a particular temperature, 12.0 moles of so3 is placed into a 3.0-l rigid container, and the so3 dissociates by the reaction 2so3(g) 34 2so2(g) 1 o2(g) at equilibrium, 3.0 moles of so2 is present. calculate k for this reaction.

The value of k for the reaction is 0.055.

In the reaction, the dissociate to form and .

2 moles of sulfur trioxide will form 2 moles of sulfur dioxide and 1 mole of oxygen.

According to the ICE setup :

4                  0           0     I

-2x               +2x        x     C

                     1                  E

Since there were 3 moles of   at the equilibrium.

2x = 3 moles.

x = 1.5 moles.

The initial amount of = 12 moles

At equilibrium, there has been a 2x reduction.

The amount of   = 12 - 2x

= 12 - 3

= 9 moles.

The amount of at equilibrium is 2x

= 3 moles.

The amount of at equilibrium is x.

= 1.5 moles.

k can be calculated as:

k =

k = 0.055.

The value of k for the reaction is 0.055.

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.

hope this .
