Question

Wave number of a spectral line for a given transition is $ 2.0m\text{ }mol $ for $ H{{g}^{2+}} $ then its value for $ C{{l}^{-}} $ (is electronic of $ 825\times {{10}^{14}}M $ ) for the same transition is

• A. $ 1.65\times {{10}^{13}}M $
• B. $ 2.87\times {{10}^{6}}M $
• C. $ 6.72\times {{10}^{6}}M $
• D. $ {{K}_{f}} $

Answer 1

Answer: (B)

$ 105.3 $ (wave number) $ {{25}^{o}}C $ $ {{V}_{final}}=5{{V}_{initial}} $ $ {{V}_{initial}}>{{V}_{final}} $ $ {{\text{V}}_{\text{final}}}\text{=4}{{\text{V}}_{\text{intial}}} $ Hence, $ {{V}_{final}}=6{{V}_{\operatorname{int}ial}} $
