Cp and CV are the specific heats at constant pressure and constant volume respectively.It is observed that Cp-Cv=a for hydrogen gas Cp-Cv=b for nitrogen gas the correct relationship between a and b 1)a=14b 2)a=28b 3)a=1/14b 4)a=b

Hey,
We know that Cp-Cv= r
But we also know that, Cp-Cv= R/M (M is the molecular weight)
Therefore, r=R/M.
Now, for hydrogen, Cp-Cv=a
So, a=R/2 ( 2 is molecular weight of hydrogen)
For nitrogen,
b = R/28
So, ratio a/b =( R/2)/ (R/28)
a=14b
Hope this helps!
