Arrhenius Equation

Calculate 2...

Question

Calculate $2 \times K_{p}$ for,
$N H_{3} ⇌ 1 / 2 N_{2} + 3 / 2 H_{2}$
(Given : $N_{2} + 3 H_{2} ⇌ 2 N H_{3}$ ; $0.5 {l i t r e}^{2} {m o l}^{- 2}$ at $400$ .) (units in atm)

Solution

$K_{c} = \frac{1}{\sqrt{0.5}} = 1.414 m o l / L$

$Δ n = 1.5 + 0.5 - 1 = 1$

$K_{p} = K_{c} (R T)^{Δ n} = 1.41 \times (0.0821 \times 400)^{1} = 46.5 a t m$

$∴ 2 \times K = 2 \times 46.5 = 93$

Hence, the correct option is $93$
