Answer:
- 1.5 × 10⁻⁹M
Explanation:
<u>1. Equilibrium equation</u>
- H₂(g) + Br₂(l) ⇄ 2HBr(g)
<u>2. Equilibrium constant</u>
The liquid substances do not appear in the expression of the equilibrium constant.
<u>3. ICE table.</u>
Write the initial, change, equilibrium table:
Molar concentrations:
H₂(g) + Br₂(l) ⇄ 2HBr(g)
I 0.400 0
C - x +2x
E 0.400 - x 2x
<u>4. Substitute into the expression of the equilibrium constant</u>
<u>5. Solve the quadratic equation</u>
- 192,000,000 - 480,000,000x = 4x²
- x² + 120,000,000x - 48,000,000 = 0
Use the quadratic formula:
The only valid solution is x = 0.39999999851M
Thus, the final concentration of H₂(g) is 0.400 - 0.39999999851 ≈ 0.00000000149 ≈ 1.5 × 10⁻⁹M
One of the most likely products for the reaction would be
The reaction between and
yields 3 products which are
(a precipitate),
, and
as shown by the equation below:
One of the products precipitates out of the solution to give the reaction a precipitation reaction look.
