Answer:
0.09425
Explanation:
The reactant is in solid phase and therefore has zero partial pressure.
The products have the same mole ratio (1:1) and will have the same partial pressure = 1/2 × 0.614 atm = 0.307 atm
Kp = (NH3)(H2S) = 0.09425
Answer:
Option D. T
Explanation:
Enthalpy change (ΔH) is simply the difference between the heat content of the product (Hp) and the heat content of the reactant (Hr). Mathematically, it is expressed as:
Enthalpy change (ΔH) = Heat of product (Hp) – heat of reactant (Hr)
ΔH = Hp – Hr
From the diagram given above, the difference between the heat content of product and the heat content of reactant is T.
Therefore, the enthalpy change of the reaction is T.
For [Ca +2 ]:
0.0010 mol/l · 0.05 l =
For [ SO4 -2 ] :
0.01 mol/l · 0.05 l =
Cumulative volume:
50 ml + 50 ml = 10 ml = 0.1 l
[Ca +2 ] =
[SO4 - 2] =
Qc for CaSO4:
Qc =
This is less than Ksp of CaSO4.
Answer:
C ) No precipitation will occur.
