Ahat [919]

Answer:

0.328 atm

Explanation:

Kp is the equilibrium constant calculated based on the pressure, and it depends only on the gas substances. It will be the multiplication of partial pressures of the products raised to their coefficients divided by the multiplication of partial pressures of the reactants raised to their coefficients.

For the equation given, the stoichiometry is 1 mol of NH₃ for 1 mol of H₂S, so they will have the same partial pressure in equilibrium, let's call it p. So:

Kp = pxp

0.108 = p²

p = √0.108

p = 0.328 atm, which is the partial pressure of the ammonia.

Why is it better to allow the solvent front to move almost to the top of a paper strip rather than stopping it at the halfway po
m_a_m_a [10]

Answer:

To allow all the elements or compounds to separate complete.

Explanation:

In chromatography, the compounds need some space and time to separate, one from each other, if you  just use the half of the paper strip maybe you will not notice the different spots of compounds. Remember all the substances have different affinity for the solvents, that means, some react very quickly but others need more time as the colors that conform the black color in an ink.

What is the relationship between reaction rate and reaction time
Natali [406]

Answer:

The reaction rate is inversely proportional to the reaction time.

Explanation:

  • The reaction rate is the change of the concentration of reactants and products with the time.

<em>∵ Reaction rate = - Δ[reactants]/Δt = Δ[products]/Δt.</em>

<em>∴ The reaction rate is inversely proportional to the time, as the reaction rate increases it will take a lower time.</em>
