CO(g)+2H2(g)⇌CH3OH(g)CO(g)+2H2(g)⇌C H3OH(g) This reaction is carried out at a different temperature with initial concentrations of [CO]=0.27M[CO]=0.27M and [H2]=0.49M[H2]=0.49M. At equilibrium, the concentration of CH3OHCH3OH is 0.11 MM. Find the equilibrium constant at this temperature.

9.4

Explanation:

The equation for the reaction can be represented as:

   +         ⇄  

The ICE table can be represented as:

                                     +         ⇄  

Initial                          0.27             0.49              0.0

Change                      -x                  -2x                 x

Equilibrium               0.27 - x         0.49 -2x          x

We can now say that the concentration of   at equilibrium is x;

Let's not forget that at equilibrium   = 0.11 M

So:

x =  [] = 0.11 M

[] = 0.27 - x

[] = 0.27 - 0.11

[] = 0.16 M

[] = (0.49 - 2x)

[] = (0.49 - 2(0.11))

[] = 0.49 - 0.22

[] = 0.27 M

= 9.4

∴ The equilibrium constant at that temperature = 9.4

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).

explanation:

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.
