Is a forward or reverse reaction favored? Review the reversible reactions given, along with the associated equilibrium constant Kat room temperature. In each case, determine whether the forward or reverse reaction is favored. CH3COOH – CH3C00++ H+ Choose... Ka=1.8 x 10-5 Choose... AgCl → Agt + Cl Ksp=1.6 x 10-10 Al(OH)3 + A13+ + 30H Choose... Ksp=3.7 x 10-15 A+BAC Choose... K=4.9 x 103

(a) : reverse reaction is favored.

(b) : reverse reaction is favored.

(c) : reverse reaction is favored.

(d) : forward reaction is favored.

Explanation:

Hello,

(a) :

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (acetic acid) will tend to have a higher concentration.

(b) :

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (silver chloride) will tend to have a higher concentration.

(c)

In this case, since the Ka is lower than 1, we infer the reverse reaction is favored since the reactant (aluminium hydroxide) will tend to have a higher concentration.

(d)

In this case, since the Ka is greater than 1, we infer the forward reaction is favored since the product (C) will tend to have a higher concentration.

Regards.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
