The process: 2X(g) ⇌ X2(g) has Kp = 1.25 × 109 atm-1. If 'X' atoms are taken at 1 atm pressure, what should be the equilibrium pressure of 'X'?
Options:
Answer:
B
Solution:
Kp is very large, so X is almost fully dimerised: PX2 ≈ 0.5 atm Kp = PX2/PX2 gives PX2 = 0.5/(1.25 × 109) = 4 × 10-10
PX = 2 × 10-5 atm
This is option (b).
