Type: MCQ-numerical-Hard-Class 11
For the equilibrium PCl₅(g) ⇌ PCl₃(g) + Cl₂(g), if the equilibrium constant Kc is 1.8 and initial concentration of PCl₅ is 3 M, what is the equilibrium concentration of Cl₂?
A
1.59 M
B
2.00 M
C
1.41 M
D
0.50 M
Correct Answer
Option A
Detailed Explanation
Using the given equation x² / (3-x) = 1.8, solve for x to find that x = 1.59 M, which is the equilibrium concentration of Cl₂.
