Kp = Kc (RT)Δ n , Δ n = 4 - 3 = 1 0.05 =Kc R × 1000 KC = 5 × 10-5 R -1'

Q. At $1000 K$ , the value of $K_{p}$ for the reaction: $A (g) + 2 B (g) ⇌ 3 C (g) + D (g)$ is $0.05$ atmosphere. The value of $K_{c}$ in terms of $R$ would be:

$20000 R$

$0.02 R$

$5 \times 1 0^{- 5 +} R$

$5 \times 1 0^{- 5} \times R^{- 1}$

$K_{p} = K_{c} (RT)^{Δ n}, Δ n = 4 - 3 = 1$
$0.05 = K_{c}^{R} \times 1000$
$K_{C} = 5 \times 1 0^{- 5} R^{- 1}$ '
