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} $
