Answer:
28.6
Explanation:
Step 1: Write the balanced reaction at equilibrium
CO(g) + Cl₂(g) ⟺ COCl₂(g)
Step 2: Calculate the equilibrium partial pressure (in atm) of phosgene?
We will use the expression for the pressure equilibrium constant (Kp)
Kp = pCOCl₂ / pCO × pCl₂
pCOCl₂ = Kp × pCO × pCl₂
pCOCl₂ = 1.49 × 10⁸ × 4.38 × 10⁻⁴ × 4.38 × 10⁻⁴ = 28.6
Answer:
a. 0,035M
Explanation:
For the reaction:
Ba(OH)₂(s) ⇄ Ba²⁺(aq) + 2OH⁻(aq)
Ksp is defined as:
Ksp = [Ba²⁺] [OH⁻]²
5x10⁻³ = [Ba²⁺] [OH⁻]²
if is added a solution of 1M of Ba²⁺:
5x10⁻³ = [1M] [OH⁻]²
The addition of barium hydroxide Ba(OH)₂ gives:
[Ba²⁺] = 1M + x
[OH⁻]² = 2x
Replacing:
5x10⁻³ = [1 + x] [2x]²
5x10⁻³ = 4x² + 4x³
Solutions are:
x = -1,00 M
x = -0,036 M
<em><u>x = 0,035 M</u></em> → Right answer, there are not negative concentrations.
Thus, solubility is
<em>a. 0,035M</em>
