Initial1 mole -
At equilirbium 1-x mole x mole2x mole
V = 25 L and
T = 300 K.
At equilibrium, P = 1.9 atm
Total moles at equilibrium, n = 1 + 2x
V = 25 L
T = 300 K
Using, PV = nRT
1.9 × 25 = (1 + 2x) × 0.08206 × 300
x = 0.465
Now;Partial pressure of AB2 at equilibrium =
Using ;
= 0.728
KP = 0.73
Kp = 73 × 10-2
So; x = 73
