Answer:
Kp = 0.0146
Explanation:
We can solve this equilibrium problem using an ICE Table. There are 3 stages: I(Initial), C(Change) and E(Equilibrium). Only <em>gases</em> and <em>aqueous species</em> participate in the equilibrium.
NH₄CO₂NH₂ ⇄ 2 NH₃(g) + CO₂(g)
I 0 0
C +2x +x
E 2x x
<em>Total gas pressure is equal to the sum of partial pressures at equilibrium.</em>
pNH₃ + pCO₂ = 0.463 atm
2x + x = 0.463 atm
3 x = 0.463 atm
x = 0.154 atm
Then,
pNH₃ = 0.308 atm
pCO₂ = 0.154 atm
We can replace this data in the Kp expression.
