Equilibrium Question 547
Question: For the reaction $ PCl_3(g)+Cl_2(g) $ ⇌ $ PCl_5(g) $ at $ 250^{o}C $ , the value of $ K_{c} $ is 26, then the value of $ K_{p} $ on the same temperature will be [MNR 1990; MP PET 2001]
Options:
A) 0.61
B) 0.57
C) 0.83
D) 0.46
Show Answer
Answer:
Correct Answer: A
Solution:
$ K_{p}=K_{c}{{(RT)}^{\Delta n}} $
$ =26,{{(0.0821\times 523)}^{-1}}=0.61 $ . $ \Delta n_{g}=1-2=-1 $
