Answer:
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
Explanation:
Given that Kp = 0.116atm
NH₄(NH₂CO₂)(s) ⇄ 2NH₃(g) + CO₂(g)
2x atm xatm
Pt = PNH₃ PCO₂
0.116 = 2x + x
0.116 = 3x
x = 0.116/3
x = 0.039 atm
PNH₃ = 2x =2(0.039) = 0.078 atm
PCO₂ = x = 0.039 atm
Now,
KP = PNH₃² × PCO₂
= 0.078² × 0.039 atm³
= 2.37 × 10⁻⁴ atm³
the value of Kp at 25°C is 2.37 × 10⁻⁴atm³
