The reaction 20F2(9) —2F2(9) + O2(9) has an equilibrium constant K, in terms of pressures) at 25°C of 6.19x10-4. Calculate the c
Vsevolod [243]

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>

I hope it helps!

If the concentration of a dilute solution of nitric acid is 0. 0001 m. What is the ph of that solution?
gayaneshka [121]

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 (\frac{1}{10000})

     = - 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.
