Answer:
As K >>> 1, the reaction will shift to the products
Explanation:
To know the direction of any reaction you must calculate the equilibrium constant, K. If K is < 1, the reaction will shift to the reactants and if k > 1 the reaction will shift to the products.
With the reactions:
<em>HSO₄⁻ ⇄ SO₄²⁻ + H⁺ Ka = 1.26x10⁻²</em>
And:
NH₄⁺ ⇄ NH₃⁺ + H⁺ Ka = 5.6x10⁻¹⁰
The inverse reaction:
<em>NH₃⁺ + H⁺ ⇄ NH₄⁺ 1/Ka = 1.8x10⁹</em>
<em />
The sum of the reactions:
HSO₄⁻ + NH₃⁺ + H⁺ ⇄ NH₄⁺ + SO₄²⁻ + H⁺ K = 1.26x10⁻² ₓ 1.8x10⁹ = 2.3x10⁷
<h3>As K >>> 1, the reaction will shift to the products</h3>
Answer:
D: Increasing temperature
Explanation:
From collision theory, we know that the more the increase in collisions, the faster the rate of the chemical reaction.
Now, the amount of solid solute in a solvent will change with a corresponding change in temperature. What we mean is that, the higher the temperature increases, the higher the number of collisions between the solvent molecules as well as leading to an increase in the solute particles which will mean an increase in the amount of the solid solute dissolved. The correct answer is option D.
Explanation:
Transfer of mass A into stagnant film B depends on the availability of driving force.
Whereas driving force is the pressure difference at the surface of A and the bulk.
As, 
Therefore, putting the given values into the above formula as follows.
= 
= 0.132 
Thus, we can conclude that the flux of A from a surface into a mixture of A and B is 0.132
The actual yield is 489.8g of magnesium nitrate
