Answer:
A molecular formulae________
will tell you how many and what
kinds of atoms are in a molecule, but not how they are
arranged.
Answer:
The correct answer is: K'= 0.033.
Explanation:
The formation of HI from H₂ and I₂ is given by:
H₂ + I₂ → 2 HI K= 29.9
The decomposition of HI is the reverse reaction of the formation of HI:
2 HI → H₂ + I₂ K'
Thus, K' is the equilibrium constant for the reverse reaction of formation of HI. It is calculated as the reciprocal of the equilibrium constant of the forward reaction (K):
K' = 1/K = 1/(29.9)= 0.033
Therefore, the equilibrium constant for the decomposition of HI is K'= 0.033

Overall:
Nernst equation for this cell reaction at :
Where, n is number of electron exchanged and species inside third bracket represents concentrations in molarity.
Here, n = 2, and
So, plug in all the given values into above equation:
So,
As the value "0.059" varies from literature to literature and is most closest to therefore option (B) is correct.
