In which one of the following equilibria, Kp KC ?
Multiple Choice Options
- A 2NO(g) ⇋ N2(g) + O2(g)
- B 2C(s) + O2(g) ⇋ 2CO(g)
- C 2HI(g) ⇋ H2(g) + I2(g)
- D NO2(g) + SO2(g) ⇋ NO(g) + SO3(g)
Step-by-Step Verified Solution
We know,
Kp = KC(RT) ng
Kp = KC when ng = 0
Kp KC when ng 0 and T 12 K
In this reaction, 2C(s) + O2(g) ⇋ 2CO(g)
ng = 1, so Kp KC
Kp = KC(RT)
Kp = KC when
Kp
In this reaction, 2C(s) + O2(g) ⇋ 2CO(g)
