Question

At 55°C and 1 atm, 50.3% of N₂O₄ decomposes as per the following reaction

N₂O₄(g) ⇌ 2NO₂(g) 

At what pressure, the equilibrium mixture has the amounts of NO₂ and N₂O₄ in the ratio 1 : 10

Answer 1

N₂O₄(g) ⇌ 2NO₂(g)

Given x = 0.503 and P = 1 atm

K_p = 1.3548 atm

At pressure ‘P_x ’, the value of K_p remains same, as equilibrium constant K_p is independent of pressure
