Q2 TY Write the equilibrium expression... [FREE SOLUTION]

Chapter 8: Q2 TY (page 165)

Write the equilibrium expression for ${Ca}^{2 +} + 2 {Cl}^{-} 鈫� {Cacl}_{2} (aq)$ with activity coefficients.

Short Answer

Expert verified

The equilibrium expression is $K = \frac{A_{C a C}}{位_{C a^{2 +}} X_{C^{-}}^{2}} = \frac{[C a C l_{2}]}{[C a^{2 +}] 纬_{C a^{2}} + {[C l^{-}]}^{2} 纬_{C l^{-}}}$ .

Step by step solution

Concept used.

Equilibrium expression:

The equilibrium equation determines the ratio of products to reactants.

$aA + bB 鈫� cC + dD A_{A}^{2} A_{B}^{D} {| A |}^{2} 纬_{A}^{2} {| B |}^{0} 纬_{B}^{b}$

where,

-activity of species

[] -concentration of species

$纬$ - activity coefficient of species.

Step 2: Calculate the ionic strength of 1mMCaCl2.

Given reaction,

${Ca}^{2 +} + 2 {Cl}^{-} 鈫� {Cacl}_{2} (aq)$

The equilibrium expression by the activity of all species

$K = \frac{A_{C O C}}{A_{C 2} 2 + A_{a}^{2}} = \frac{|C a C h_{2}| 纬_{C a C}}{[C a^{2 +}] 纬_{C a^{2} 2} + C r | h_{C}^{2}}$

The equilibrium expression for the given reaction was calculated using the species' activity and concentration.
