Equilibrium Question 869

Question: $ \Delta G^{0}(HI,,g)\cong +1.7,kJ $ . What is the equilibrium constant at $ 25^{o}C $ for $ 2HI(g) $ D $ H_2(g)+I_2(g) $

Options:

A) 24.0

B) 3.9

C) 2.0

D) 0.5

Show Answer

Answer:

Correct Answer: D

Solution:

$ \Delta G^{o}=-2.303\times 8.314\times {10^{-3}}\times 298\log ,K_{p} $

$ 1.7=-2.303\times 8.314\times {10^{-3}}\times 298\times \log ,K_{p} $

$ K_{p}=0.5 $
