Let's assume that change of pressure of PCl₅ is X
According to the ICE table,
PCl₅(g) ⇄ PCl₃(g) + Cl₂(g)
Initial Pressure 0.123 - -
Change -X +X +X
Equilibrium 0.123 - X X X
Kp = Ppcl₃(g) x Pcl₂(g) / Ppcl₅(g)
by substitution,
0.0121 = X × X / (0.123 - X)
0.0121 × (0.123 - X) = X²
1.4883 × 10⁻³ - 0.0121X = X²
X² + 0.0121X - 1.4883 × 10⁻³ = 0
X₁ = 0.03735 or X₂ = -0.03865
X cannot be a negative value since X is a pressure.
Hence,
X = 0.03735 atm
Hence, partial pressure of PCl₃ is 0.03735 atm
Answer:
True
Explanation:
This is the true statement .
Because There are two types of metal coagulants used : aluminium and iron.
The aluminum coagulants include aluminum sulfate, aluminum chloride and sodium aluminate.
The iron coagulants include ferric sulfate, ferrous sulfate, ferric chloride and ferric chloride sulfate.
Answer:
heat is the movement from areas of <u>high </u>temperature to areas of <u>low </u>temperature
An atom emits a photon with a wavelength of 260 nm, the atom’s energy change is 7.6 × 10^(-19) J.
<h3>
What is photon energy relationship?</h3>
The energy of photon is inversely proportional to the wave length and directly propositional the speed of light.
Mathematically, photon energy relationship can be given as
E= Energy of photon
h= Plank's constant = 
× 
c = 3 х 
λ = 
× 
× 
Thus, we find that the energy change is 7.6 × 10^(-19) J.
