Answer:
K = 4.07x10⁻³
Explanation:
Based on the reaction:
NH₄I(s) ⇄ NH₃(g) + HI(g)
You can define K of equilibrium as the ratio of concentrations of reactants and products, thus:
K = [NH₃] [HI] / [NH₄I]
But, as NH₄I is a solid, is not taken into account in the equilibrium, that means K expression is:
K = [NH₃] [HI]
As the concentrations in equilibrium of the gases is:
[NH₃] = 4.34x10⁻²M
[HI] = 9.39x10⁻²M
Equilibrium constant, K, is:
K = 4.34x10⁻²M * 9.39x10⁻²M
<h3>K = 4.07x10⁻³</h3>
I believe it has something to do with the H2O molecules, because a chemical compound is not a mixture.
Answer:
New Volume = 0.013 Liter
Explanation:
Combined Gas Law Problem
P₁V₁/T₁ = P₂V₂/T₂
P₁ = 1 atm
V₁ = 1.2 Liters
T₁ = 0°C = 273 K
P₂ = 100 atm
V₂ = V₁(P₁/P₂)(T₂/T₁)
T₂ = 15°C = (273 + 15)K = 288K
P₂ = 1.2L(1atm/100atm)(288K/273K) = 0.013 Liter
