The partial pressure is Pn = 4 * 10⁻²¹.
Each gas that makes up a mixture of gases has a partial pressure, which is the notional pressure of that gas as if it alone filled the original combination's complete volume at the same temperature.
logKp=-43. 10
The partial pressure of N2 at 1000 K is (PN2) =200 atm,
The partial pressure of N is = (Pn)
(PH2) =600 atm,
logKp=-17. 30
The reaction for the dissociation of nitrogen molecule into its element is given below:
N₂(g) ⇔ 2N(g)
The expression of equilibrium constant (KP) is,
Kp = P²n/P¹n2 ......(i)
When,
log Kp = -43.10
Kp = 10⁻⁴³°¹⁰
= 7.9 * 10⁻⁴⁴
The partial pressure of N2 at 1000 K is 200 atm,
Pn2 =200 atm,
Put value in equation (i),
7.9 * 10⁻⁴⁴ = Pn2/200atm
Pn2 = 200atm * 7.9 * 10⁻⁴⁴
Pn = 4 * 10⁻²¹
