Answer:
The concentration of F₂in equilibrium is 4,93x10⁻₃M
Explanation:
For the reaction:
2 OF₂ ⇄ 2 F₂ + O₂
The equilibrium constant, k, is defined as:
k = [F₂]²[O₂] / [OF₂]²
If you have in equilibrium [OF₂] = 2,49x10⁻² and [O₂] = 1,58x10⁻²
The concentration of F₂ is:
6,19x10⁻⁴ = [F₂]²[1,58x10⁻²] / [2,49x10⁻²]²
2,43x10⁻⁵ = [F₂]²
<em>4,93x10⁻³ = [F₂]</em>

If the concentration of a dilute solution of nitric acid is 0. 0001 M. The pH of the solution is 4.
<h3>What is pH ? </h3>
pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.
<h3>How to find the pH of the solution ?</h3>
To calculate the pH hydrogen ion it is expressed as:
pH = - log [H⁺]
So, concentration of hydrogen ion in HNO₃ is 0.0001 M.
pH = - log [0.0001]
= 
= - log (10)⁻⁴
= -4 × - log (10)
= - 4 × (-1)
= 4
Thus from the above conclusion we can say that The pH of the solution is 4.
