SATHEE: Equilibrium Question 783

Equilibrium Question 783

Question: For the reaction $H_{2} (g) + I_{2} (g) \to 2 H I (g)$ at 721 K, the value of equilibrium constant is 50, when equilibrium concentration of both is 5M. Value of $K_{p}$ under the same conditions will be

Options:

A) 0.02

B) 0.2

C) 50

D) 50 RT

Show Answer

Answer:

Correct Answer: C

Solution:

$H_{2} (g) + I_{2} (g) \to 2 H I (g)$

$K_{p} = K_{c} {(R T)}^{Δ n};$

$Δ n = 2 - 2 = 0; ∴ K_{p} = K_{c}$
