The vapor pressure of water at 25 •C is 23.8 mmHg. Write K for the vaporization of water in the unit of atm. What is Kc for the
r-ruslan [8.4K]

The degree of dissociation gives the amount of the substance that dissociated into the products. The value of Kc for water is 1.28 x 10⁻³.

<h3>What is equilibrium constant, Kc?</h3>

The equilibrium constant, Kc is the equilibrium concentration of the products over the reactants that are raised by the powers of their stoichiometry coefficient.

The reaction is shown as:

H₂​O(l) ⇋ H₂​O(g)

Kp = pressure of water = 0.03131579 atm

\rm Kp = Kc(RT)^{\Delta n}

Here Δ n = 1

Solving further,

Kp = Kc(RT)

0.03131579 = Kc(0.0821 × 298.15)

Kc =1.28 x 10⁻³

Therefore, Kc is 1.28 x 10⁻³.
