Question
IBr(g) is in equilibrium with I2(g) and Br2(g) at 150 ºC:
2 IBr(g) ⇌ I2(g) + Br2(g) K = 8.50 × 10–3
Initially, a closed vessel at 150 ºC has a partial pressure of IBr of 0.350 atm and partial pressures of I2 and Br2 each of 0.750 atm. What is the partial pressure of IBr once the system reaches equilibrium?
A.
1.01 atm
B.
1.09 atm
C.✓ Correct
1.56 atm
D.
1.82 atm
