COFCl(g) passed over a catalyst at 900°C comes to equilibrium: 2COFCl(g) ⇌ COCl2(g) + COF2(g). Analysis of the equilibrium mixture (after quick cooling to freeze the equilibrium) shows that 560 mL of the mixture (STP) contains 320 mL (STP) of (COFCl + COCl2) taking the total pressure to be 6 atm. The value of KP for the reaction is
Answer:
9.00
Solution:
Let the volumes (STP) be COFCl = a and COCl2 = COF2 = b a + 2b = 560 and a + b = 320
b = 240 mL and a = 80 mL
KP = (PCOCl2)(PCOF2)/(PCOFCl)2 = [(240/560)(6)]2/[(80/560)(6)]2
KP = (240/80)2 = 9
KP = 9
