The Bohr model proposed that electrons could just have characterized vitality levels thus when rotting back to a lower vitality level discharge a specific measure of vitality. Since the measure of vitality could be changed over to a specific recurrence then particular emanation lines were found in the electromagnetic range. Alternate speculations couldn't clarify the discharge lines.
Work is labor and energy is useful for it because you need energy to work unless you will be tired
Answer:
C) [PCl5] = 0.0280 M, [PCl3] = 0.222 M, [Cl2] = 0.222 M
Explanation:
Moles of [PCl₅] = 0.250 M
Considering the ICE table for the equilibrium as:
PCl₅ (g) ⇔ PCl₃ (g) + Cl₂ (g)
t = o 0.250
t = eq -x x x
---------------------------------------------
--------------------------
Moles at eq: 0.250-x x x
The expression for the equilibrium constant is:
So,
x = 0.222 M
Equilibrium concentrations :
[PCl₃] = [Cl₂] = 0.222 M
[PCl₅] = 0.250 - 0.222 = 0.280 M
<u>Option C is correct.</u>
