Equilibrium Question 783

Question: For the reaction $ H_2(g)+I_2(g)\rightarrow 2HI(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)\rightarrow 2HI(g) $

$ K_{p}=K_{c}{{(RT)}^{\Delta n}}; $

$ \Delta n=2-2=0;\therefore K_{p}=K_{c} $
